Variants can be filtered using the track controls to show subsets of the data by either EVA Sequence Ontology (SO) term, UCSC-generated functional effect, or by color, which bins the UCSC functional effects into general classes.

Mouse-over

Mousing over an item shows the ucscClass, which is the consequence according to the Variant Annotation Integrator, and the aaChange when one is available, which is the change in amino acid in HGVS.p terms. Items may have multiple ucscClasses, which will all be shown in the mouse-over -in a comma-separated list.

Track colors

Variants are colored according to the most potentially deleterious functional effect prediction according to the Variant Annotation Integrator. Specific bins can be seen in the Methods section below.

Sequence Ontology (SO)
Variants are classified by EVA into one of the following sequence ontology terms:

substitution — A single nucleotide in the reference is replaced by another, alternate allele.
deletion — One or more nucleotides are deleted. The representation in the database is to display one additional nucleotide in both the Reference field (Ref) and the - Alternate Allele field (Alt). E.g. a variant that is a deletion of an A - maybe be represented as Ref = GA and Alt = G. + Alternate Allele field (Alt). E.g., a variant that is a deletion of an A + may be represented as Ref = GA and Alt = G.
insertion — One or more nucleotides are inserted. The representation in the database is to display one additional nucleotide in both the Reference field (Ref) and the - Alternate Allele field (Alt). E.g. a variant that is an insertion of a T may + Alternate Allele field (Alt). E.g., a variant that is an insertion of a T may be represented as Ref = G and Alt = GT.
delins — Similar to a tandem repeat, in that the runs of Ref and Alt Alleles are of different length, except that there is more than one type of nucleotide, e.g., Ref = CCAAAAACAAAAACA, Alt = ACAAAAAC.
multipleNucleotideVariant — More than one nucleotide is substituted by an equal number of different nucleotides, e.g., Ref = AA, Alt = GC.
sequence alteration — A parent term meant to signify a deviation from another sequence. Can be assigned to variants that have not been characterized yet.
Methods
Data were downloaded from the European Variation Archive EVA current_ids.vcf.gz files corresponding to the proper assembly.

For every organism, the NCBI RefSeq curated models were used when available, followed by ensembl genes, and finally UCSC mapping of RefSeq when neither of the previous models were possible.
Variants were then colored according to their predicted consequence in the following fashion:

Protein-altering variants and splice site variants - exon_loss_variant, frameshift_variant, inframe_deletion, inframe_insertion, initiator_codon_variant, missense_variant, splice_acceptor_variant, splice_donor_variant, splice_region_variant, stop_gained, stop_lost, coding_sequence_variant, transcript_ablation

Synonymous codon variants - synonymous_variant, stop_retained_variant

Non-coding transcript or Untranslated Region (UTR) variants - 5_prime_UTR_variant, 3_prime_UTR_variant, complex_transcript_variant, non_coding_transcript_exon_variant

Intergenic and intronic variants - upstream_gene_variant, downstream_gene_variant, intron_variant, intergenic_variant, NMD_transcript_variant, no_sequence_alteration

No functional annotations were provided by the EVA (e.g., missense, nonsense, etc). These were computed using UCSC's Variant Annotation Integrator (Hinrichs, et al., 2016). Amino-acid substitutions for missense variants are based on RefSeq alignments of mRNA transcripts, which do not always match the amino acids predicted from translating the genomic sequence. Therefore, in some instances, the variant and the genomic nucleotide and associated amino acid may be reversed. E.g., a Pro > Arg change from the perspective of the mRNA would be Arg > Pro from the perspective of the genomic sequence. Also, in bosTau9, galGal5, rheMac10, -and danRer11 the mitochondrial sequence was removed or renamed to match UCSC. +and danRer11, the mitochondrial sequence was removed or renamed to match UCSC.
