Invitae | RCV001037870 | SCV001201304 | uncertain significance | Autosomal recessive distal spinal muscular atrophy 1; Charcot-Marie-Tooth disease axonal type 2S | 2023-08-10 | criteria provided, single submitter | clinical testing | 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 IGHMBP2 protein function. This sequence change replaces arginine, which is basic and polar, with lysine, which is basic and polar, at codon 333 of the IGHMBP2 protein (p.Arg333Lys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with IGHMBP2-related conditions. ClinVar contains an entry for this variant (Variation ID: 836684). 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. |
