The p.Arg278Ter variant is a well-documented variant that has been reported in individuals with oculocutaneous albinism (OA) in multiple ethnic groups. Across a selection of the available literature, the p.Arg278Ter variant has been identified in 28 probands in a homozygous state, six probands in a compound heterozygous state, and three probands in a heterozygous state (Tripathi et al. 1993; Gershoni-Baruch et al. 1994; Goto et al. 2004; Sundaresan et al. 2004; Chaki et al. 2005; Renugadevi et al. 2010; Park et al. 2012; Wei et al. 2013; Wang et al. 2015). The p.Arg278Ter variant was absent from 137 control individuals and is reported at a frequency of 0.00115 in the South Asian population of the Exome Aggregation Consortium. Haplotype analysis suggested that p.Arg278Ter may be a founder variant (Chaki et al. 2005; Jaworek et al. 2012). Based on the collective evidence and the potential impact of stop-gained variants, the p.Arg278Ter variant is classified as pathogenic for oculocutaneous albinism. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.

The variant is found to be disease-causing by MutationTaster2. The reference codon is conserved across species. The observed variant has previously been reported in patients affected with oculocutaneous albinism (Wang et al., 2015)
