Description

The KRT16 c.379C>T variant is predicted to result in the amino acid substitution p.Arg127Cys. This variant has been reported in individuals with non-epidermolytic palmoplantar keratoderma (Shamsher et al. 1995. PubMed ID: 8595410) and in individuals with pachyonychia congenita (Fu et al. 2010. PubMed ID: 21160496; Samuelov et al. 2020. PubMed ID: 31823354; Smith et al. 2005. PubMed ID: 16250206). Of note, other variants impacting p.Arg127 have also been reported in individuals with pachyonychia congenita (Fu et al. 2010. PubMed ID: 21160496). This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare, and is reported as pathogenic by several laboratories in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/14601/). This variant is interpreted as pathogenic.
