Genes affected

LRSAM1 (HGNC:25135): (leucine rich repeat and sterile alpha motif containing 1) This gene encodes a ring finger protein involved in a variety of functions, including regulation of signaling pathways and cell adhesion, mediation of self-ubiquitylation, and involvement in cargo sorting during receptor endocytosis. Mutations in this gene have been associated with Charcot-Marie-Tooth disease. Multiple transcript variants encoding different isoforms have been identified for this gene.

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 35 of the LRSAM1 protein (p.Asp35Asn). 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. 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 LRSAM1 protein function. ClinVar contains an entry for this variant (Variation ID: 408264). This variant has not been reported in the literature in individuals affected with LRSAM1-related conditions. This variant is present in population databases (rs551183702, gnomAD 0.03%). -
