Genes affected

SH3TC2 (HGNC:29427): (SH3 domain and tetratricopeptide repeats 2) This gene encodes a protein with two N-terminal Src homology 3 (SH3) domains and 10 tetratricopeptide repeat (TPR) motifs, and is a member of a small gene family. The gene product has been proposed to be an adapter or docking molecule. Mutations in this gene result in autosomal recessive Charcot-Marie-Tooth disease type 4C, a childhood-onset neurodegenerative disease characterized by demyelination of motor and sensory neurons.

This sequence change replaces glycine, which is neutral and non-polar, with cysteine, which is neutral and slightly polar, at codon 1283 of the SH3TC2 protein (p.Gly1283Cys). This variant is present in population databases (rs370844006, gnomAD 0.002%). This missense change has been observed in individual(s) with clinical features of SH3TC2-related conditions (PMID: 32376792). ClinVar contains an entry for this variant (Variation ID: 655809). 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 not expected to disrupt SH3TC2 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
