Description

This missense variant replaces serine with phenylalanine at codon 3448 of the RYR1 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.85, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with autosomal dominant malignant hyperthermia in the literature, although it is associated with other phenotype(s) (ClinVar variation ID: 12991). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Due to insufficient evidence, this variant is classified as a Variant of Uncertain Significance for autosomal dominant malignant hyperthermia.
