Description

For these reasons, this variant has been classified as Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt CAPN3 protein function. ClinVar contains an entry for this variant (Variation ID: 195450). This missense change has been observed in individual(s) with clinical features of autosomal recessive limb-girdle muscular dystrophy (PMID: 17562833, 30919934). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 712 of the CAPN3 protein (p.Leu712Phe).
