OMIA 001821-9593 : Coat colour, albinism, oculocutaneous type IV in Gorilla gorilla
By comparing Snowflake's 20 candidate mutations (see Mapping section) with genome sequence from two other gorillas, Prado-Martinez et al. (2013) discovered that just one of these mutations (a missense mutation in SLC45A2; chr5_33944794_C/G; pGly518Arg) was unique to Snowflake. Sequencing this gene in Snowflake and his offspring confirmed this mutation as causal.Clinical features: As summarised by Prado-Martinez et al. (2013): "Snowflake presented the typical properties of albinism as seen in humans: white hair, pink skin, blue eyes, reduced visual acuity and photophobia. Given his lack of pigmentation and thus reduced protection from UV light, the aged albino gorilla developed squamous-cell carcinoma that led to his euthanasia in 2003." Associated gene:

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.
