Description

This sequence change replaces cysteine with serine at codon 255 of the FHL1 protein (p.Cys255Ser). The cysteine residue is moderately conserved and there is a moderate physicochemical difference between cysteine and serine. This variant is not present in population databases (ExAC no frequency). This variant has been observed to segregate with Emery-Dreifuss muscular dystrophy and hypertrophic cardiomyopathy in a family (PMID: 26857240) and with distal myopathy and hypertrophic cardiomyopathy in a different family (PMID: 25246303). ClinVar contains an entry for this variant (Variation ID: 222635). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: Deleterious; PolyPhen-2: Probably Damaging; Align-GVGD: Class C0). For these reasons, this variant has been classified as Pathogenic.
