Description

The TYR c.272G>T variant is predicted to result in the amino acid substitution p.Cys91Phe. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. Alternate substitutions of this amino acid (p.Cys91Tyr and p.Cys91Ser) have been reported in individuals with oculocutaneous albinism (Shakil et al. 2019. PubMed ID: 30996339; Chaki et al. 2011. PubMed ID: 20861851). This variant has been detected in trans with a pathogenic TYR variant in an individual undergoing genetic testing for oculocutaneous albinism at PreventionGenetics (internal data). Given the evidence, we interpret c.272G>T (p.Cys91Phe) as likely pathogenic.
