FlyBase:Allele Report

Last Updated: 29th May 2015

The Allele Report contains the information for an individual allele.

An allele is a variant of a gene, often induced by mutagenic means. An allele may be defined by genetic/phenotypic characteristics, e.g. by complementation analysis, or in terms of alterations mapped to the known sequence of that gene, or both.

As well as including allele reports for classical mutant alleles and natural variants, e.g. electrophoretic variants, FlyBase also includes reports for alleles that have been introduced into Drosophila via transgenic constructs. See the Nontraditional alleles documentation for a detailed description of these alleles.

This is a field-by-field guide to the information provided in the Allele Report.

FlyBase attributes data to the publication that reported it, so that users can easily refer back to the original publication if they wish. Thus, where possible in the fields below, the publication(s) that are the source of the information are listed, typically in parentheses to the right of the data. The exception in the Allele Report is the General Information section which contains a summary of the identity of the allele.

General Information

Symbol	The valid symbol that is used in FlyBase for the allele. The first part of the symbol (before the '\') is the standard prefix for the species (from the Species Abbreviations list). For species other than D.melanogaster, the species prefix is displayed wherever the allele symbol is used throughout FlyBase. For D.melanogaster alleles, the species prefix is only displayed in the General Information section at the top of a Report.
Name	The valid full name that is used in FlyBase for the allele.
Feature type	The type of feature described in the report. In this case, "allele".
Associated Insertion(s)	If the allele is associated with an insertion of DNA, the insertion symbol is displayed in this field. The inserted DNA may be a natural transposable element e.g. P-element, a transposable-element based transgenic construct, e.g. P{lacW}, or exogenous DNA inserted via non-transposable element-based means (e.g. homologous recombination), e.g. TI{GAL4}. Clicking on an insertion symbol will take you to the relevant Insertion Report. An allele is associated with an insertion if any one or more of the following criteria apply: - the insertion results in a mutant phenotype by affecting expression of the gene into which it is inserted - the insertion is within the transcribed extent of a gene - the allele represents an open reading frame carried in the insertion, where its expression is influenced by a regulatory region in the genome where it is inserted e.g. GAL4 enhancer trap allele.
Species	The organism that the allele originates from, with the initial letter of the genus and the full species name listed.
FlyBase ID	The Primary FlyBase identifier number of the allele, used to uniquely identify the allele in the database. An allele may also have any number of Secondary FlyBase identifier numbers, which are listed in the Secondary FlyBase IDs section of the Allele Report.
Associated gene	The gene which the mutant affects. Clicking on the gene symbol will take you to the relevant Gene Report
Carried in Construct	If the allele is carried in a transgenic construct, the transgenic construct symbol is displayed in this field. Clicking on a transgenic construct symbol will take you to the relevant Recombinant Construct Report.
Also Known As	A list of up to 10 commonly used symbol synonyms for the gene. (This list is made computationally, based on the frequency of alternative symbols that have been curated from the literature.). This field is only displayed on an individual Allele Report if it contains data.
Key Links	Link to the corresponding page at the Alliance of Genome Resources
Genomic Maps (JBrowse)	A JBrowse image showing the location of the mutation on the genome. This field is only displayed if the allele, or an insertion associated with the allele, has been mapped to the genome. The "JBrowse" link goes to a fully interactive JBrowse view of the same region.
Allele class	A summary list (without the publications that were the source of the information) of controlled vocabulary terms from the FlyBase controlled vocabulary that describe the class of the allele, e.g. "hypomorph" or "gain of function". For a list of allele class terms together with the associated publications, see the Allele class field in the Nature of the Allele section of the Allele Report.
Mutagen	A summary list (without the publications that were the source of the information) of controlled vocabulary terms from the FlyBase controlled vocabulary that describe the origin of the allele, typically the mutagen(s) used to induce the mutant allele or the type of in vitro mutagenesis method used to create it. For a list of mutagen terms together with the associated publications, see the Mutagen field in the Nature of the Allele section of the Allele Report.

Nature of the Allele

Allele class	A full list (including the publications that were the source of the information) of controlled vocabulary terms from the FlyBase controlled vocabulary that describe the class of the allele, e.g. "hypomorph" or "gain of function".
Mutagen	A full list (including the publications that were the source of the information) of controlled vocabulary terms from the FlyBase controlled vocabulary that describe the origin of the allele, typically the mutagen(s) used to induce the mutant allele or the type of in vitro mutagenesis method used to create it.
Mutations Mapped to the Genome - Curation Data	A table listing features associated with the allele that have been mapped to the genome and form part of the annotation of the gene. The table lists the type of feature in the first column. The second column contains its location on the genome. The third column lists the evidence type, any associated mapping information, and any comments related to mapping the feature. The fourth column lists the reference used to map the feature.
Mutations Mapped to the Genome - Variant Molecular Consequences	Variants data from FlyBase are run through the Ensembl VEP (Variant Effect Predictor) pipeline, and the results are displayed in a table. The VEP algorithm considers the genomic location, mutation type, and nucleotide change of a variant to calculate the molecular consequence on all of the overlapping transcripts affected by the variant. In addition to reporting the molecular change to the transcripts and encoded CDS, it assigns a Sequence Ontology (SO)-based consequence term to each variant/transcript combination. The table displays, for each variant, all genes that are potentially affected by that variant, the allele associated with the variant that is the subject of the report, and the predicted consequences to all affected transcripts. This is the result of a collaboration between FlyBase, Alliance of Genome Resources and Ensembl.
Associated Sequence Data	A table of sequence accession numbers associated with the allele. Clicking on the accession number will take you to the appropriate entry in the external database from which they are derived. The table contains accession numbers from the following databases: DDBJ/EMBL/GenBank - nucleic acid accession number and associated protein ID number (if applicable). UniProtKB/Swiss-Prot - protein accession number. UniProtKB/TrEMBL - protein accession number. These accession numbers are FlyBase curated links.
Progenitor genotype	For classical alleles, this is the mutant chromosome(s) on which the allele was induced, where the progenitor is relevant to the derivative allele. The progenitor is usually another mutant allele of the same gene, or a transposable element insertion. For non-traditional alleles carried in transgenic constructs, this is typically the allele that was used in vitro as the progenitor. Clicking on the symbol of the progenitor will take you to the relevant Report page.
Caused by insertion	If the allele is associated with an insertion of DNA, the insertion symbol is displayed in this field. The inserted DNA may be a natural transposable element e.g. P-element, a transposable-element based transgenic construct, e.g. P{lacW}, or exogenous DNA inserted via non-transposable element-based means (e.g. homologous recombination), e.g. TI{GAL4}. Clicking on an insertion symbol will take you to the relevant Insertion Report. This field is only displayed on an individual Allele Report if it contains data. An allele is associated with an insertion if any one or more of the following criteria apply: - the insertion results in a mutant phenotype by affecting expression of the gene into which it is inserted - the insertion is within the transcribed extent of a gene - the allele represents an open reading frame carried in the insertion, where its expression is influenced by a regulatory region in the genome where it is inserted e.g. GAL4 enhancer trap allele.
Carried in construct	If the allele is carried in a transgenic construct, the transgenic construct symbol is displayed in this field. Clicking on a transgenic construct symbol will take you to the relevant Recombinant Construct Report. This field is only displayed on an individual Allele Report if it contains data.
Cytology	Free text comments about the cytology of the allele.
Nature of the lesion	For classical alleles, this is a free text description of the nature of the mutant lesion. For non-traditional alleles carried in transgenic constructs, this is a free text description of the overall structure of the allele at the end of the cloning process.
Associated Sequence Features	If the allele is associated with a sequence feature, such as an RNAi amplicon, the sequence feature symbol is displayed in this field. Clicking on a sequence feature symbol will take you to the relevant Sequence Feature Report. This field is only displayed on an individual Allele Report if it contains data.
Tags	This field is displayed in an Allele Report that represents an engineered tag which has been used in a transgenic construct to mark genes or their products. This includes variants of epitope tags such as the EGFP version of "Avic\GFP". The field lists the alleles that contain the tag. Clicking on the symbol will take you to the relevant Allele Report. This field is only displayed on an individual Allele Report if it contains data.
Tagged with	This field is only filled in for non-traditional alleles carried in transgenic constructs. If the allele contains an engineered tag that has been used to mark the gene or its product, the symbol of that tag is displayed in this field. Engineered tags include epitope tags such as "Avic\GFP" and function tags such as nuclear localization signals. Clicking on the tag symbol will take you to the relevant Report. This field is only displayed on an individual Allele Report if it contains data.
Caused by aberration	If the allele is caused by an aberration breakpoint within the locus, the aberration symbol is displayed in this field. Clicking on the aberration symbol will take you to the relevant Aberration Report. This field is only displayed on an individual Allele Report if it contains data.

Expression Data

Reporter Expression

A three column table with the headings Stage, Tissue/Position, and Reference. Each row in the table represents one distinct expression pattern defined by time of expression (Stage) and by location of expression (Tissue/Position). Each distinct expression pattern is attributed to the reference that reported it. Developmental stages and anatomical parts are described using controlled vocabulary (CV) terms (for valid CV terms, see the Vocabularies search page). The table is subdivided by the assay, when appropriate.

Human Disease Associations

Disease Ontology (DO) Annotations

Human Disease model data curated using disease terms from the Disease Ontology.

Models Based on Experimental Evidence	A table showing any human disease(s) that are being modelled by a given mutant or transgenic allele. The phenotype(s) being studied must recapitulate some aspect of the human disease for the allele to be considered a model. In some cases, an allele may be expected to produce a disease phenotype but does not. These unexpectedly negative results are also shown. The table consists of three columns Disease - Indicates whether or not the allele is modeling the disease ('model of' or 'DOES NOT model') followed by the name of the disease (from the Disease Ontology). Evidence - CEA (combinatorial experimental and author inference evidence used in manual assertion; ECO:0007013) is used when an annotation is made based on experimental evidence AND the disease term used agrees with that stated by the authors. This is the most commonly used evidence code. CEC (combinatorial experimental and curator inference evidence used in manual assertion; ECO:0007014) is used when an annotation is made based on experimental evidence BUT the disease term used has been determined by a curator rather than based on a statement by the authors of the paper. Use of this evidence code is relatively rare, restricted to cases where (i) the disease stated by the authors is relatively general (e.g. “amyotrophic lateral sclerosis”), but the curator can provide a more specific subtype (e.g. “amyotrophic lateral sclerosis type 6”) based on the given human gene/variant and its known relationship to a specific disease (e.g. in OMIM); or (ii) the authors have made a mistake in the given gene-to-disease relationship. If the given allele only models the disease in combination with another allele, the word with is displayed followed by the symbols of other allele(s), with hyperlinks to the relevant allele report pages. Note that any drivers that are required for the expression of transgenic alleles are not listed in this section. References - lists the reference(s) that describe the model.
Modifiers Based on Experimental Evidence	A table showing interactions of this allele with other disease-causing allele(s) The table consists of three columns Disease - the nature of the interaction ('exacerbates' or 'ameliorates' and the name of the disease (from the Disease Ontology). This column also indicates if the allele is not modifying a disease (prefixed with DOES NOT). Interaction - 'modeled by' followed by the symbol of the allele that is modeling the disease, with hyperlinks to the relevant allele report pages. References - lists the reference(s) that describes the model.
Comments on Models/Modifiers Based on Experimental Evidence	Curated comments that highlight certain features of a model, for example, when particular aspects of a disease phenotype are modeled while others are not. These comments are used sparingly to avoid duplication with phenotype information.

Phenotypic Data

Phenotypic Class

A list of statements describing the overall phenotypic class of the mutant allele.

Each statement contains a controlled vocabulary term from the phenotypic class section of the FlyBase controlled vocabulary that describes the class of phenotype that is observed in the mutant allele, e.g. visible, lethal, circadian rhythm defective.

The phenotypic class term may also be "qualified" with more controlled vocabulary term(s) that further specify the mutant phenotype, for example, describing whether the phenotype is "recessive" or "dominant", or specifying at which stage of development the phenotype is observed, e.g. second instar larval stage. These additional qualifying terms are either from the FlyBase controlled vocabulary or the Development controlled vocabulary.

If the mutant phenotype is observed in combination with another allele of the same gene, or a deficiency that affects the same gene, this second allele or deficiency is indicated in parentheses after the controlled vocabulary terms. If the allele is part of a system that requires a driver, such as the UAS-GAL4 system, the driver allele is indicated at the end of the phenotypic class statement, after a comma.

Clicking on a controlled vocabulary term will take you to the relevant CV Term Report.

Clicking on an allele or deficiency symbol will take you to the relevant Report.

Phenotype Manifest In

A list of the parts of the animal affected by the mutant allele. These terms range from the entire animal to subcellular components and are often specific for a developmental stage. Body part and cell-type terms are from the Anatomy controlled vocabulary, while terms relating to parts of the cell are cellular component terms from the Gene Ontology controlled vocabulary.

The body part term may also be "qualified" with more controlled vocabulary term(s) that further specify the mutant phenotype, for example, describing that the body part was affected in an experiment involving a "somatic clone" or is due to a "maternal effect". These additional qualifying terms are from the FlyBase controlled vocabulary.

If the mutant phenotype is observed in combination with another allele of the same gene, or a deficiency that affects the same gene, this second allele or deficiency is indicated in parentheses after the controlled vocabulary terms. If the allele is part of a system that requires a driver, such as the UAS-GAL4 system, the driver allele is indicated at the end of the phenotypic class statement, after a comma.

Clicking on a controlled vocabulary term will take you to the relevant CV Term Report.

Clicking on an allele or deficiency symbol will take you to the relevant Report.
