Categories: Pigmentation phene
Links to possible relevant human trait(s) and/or gene(s) in OMIM: 606897 (gene) , 214500 (trait)
Mendelian trait/disorder: yes

Key variant known: yes
Year key variant first reported: 2020
Species-specific name: lavender color morph
Species-specific description: "The lavender color morph in corn snakes is characterized by gray, rather than red, blotches on a pink, instead of orange, background." (Ullate-Agote et al., 2020)
Molecular basis: Ullate-Agote et al. (2020) "perform mapping-by-sequencing analyses and identify a 3.9-Mb genomic interval where the lavender variant resides. ... sequencing analyses reveal a single nucleotide polymorphism introducing a premature stop codon in the lysosomal trafficking regulator gene (LYST) that shortens the corresponding protein by 603 amino acids and removes evolutionary-conserved domains."

Variants
By default, variants are sorted chronologically by year of publication, to provide a historical perspective.
Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending
order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column
headers.
WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
