Invitae | RCV001208110 | SCV001379484 | uncertain significance | Charcot-Marie-Tooth disease axonal type 2P | 2024-01-28 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 123 of the LRSAM1 protein (p.Ile123Thr). This variant is present in population databases (rs542497718, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with LRSAM1-related conditions. ClinVar contains an entry for this variant (Variation ID: 938816). 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 LRSAM1 protein function with a negative predictive value of 80%. 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. |
Ambry Genetics | RCV003259151 | SCV003946675 | uncertain significance | Inborn genetic diseases | 2023-03-22 | criteria provided, single submitter | clinical testing | Unlikely to be causative of LRSAM1-related Charcot-Marie-Tooth disease, type 2 (AD) Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
