Description

The KIF21A c.2860C>T variant is predicted to result in the amino acid substitution p.Arg954Trp. This variant is the most commonly reported variant in individuals with autosomal dominant congenital fibrosis of the extraocular muscles (Yamada et al. 2003. PubMed ID: 14595441; Rudolph et al. 2009. PubMed ID: 19551685; Yang et al. 2010. PubMed ID: 21042561). This variant has not been documented in a large population database, indicating it is rare. This variant has been classified as pathogenic by multiple independent submitters to the ClinVar database (https://www.ncbi.nlm.nih.gov/clinvar/variation/2436). Given all the evidence, we interpret c.2860C>T (p.Arg954Trp) as pathogenic.
