Possibly relevant human trait(s) and/or gene(s) (MIM number): 203100

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2013

Cross-species summary: Congenital lack of pigment in all parts of the body. Due to a non-functional form of the enzyme tyrosinase. Also known as Oculocutaneous albinism (OCA)

Molecular basis: Cho et al. (2013) reported c.260G>A (p.Arg87Gln) as a likely causal variant for the "white lion" phenotype, reporting complete concordance of this variant with the genotyping results from "47 lions: 17 of white phenotype and 30 of wild phenotype, of which 11 were known to be carriers (heterozygotes) based on their pedigree, 14 of unknown genetic makeup, and 5 of wild phenotype from control populations where no white lions were found". FN thanks Corinne Benavides for alerting him to this discovery.
