Invitae RCV001035094 SCV001198409 uncertain significance Congenital myasthenic syndrome 12 2022-11-28 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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 GFPT1 protein function. ClinVar contains an entry for this variant (Variation ID: 834413). This missense change has been observed in individual(s) with limb-girdle myasthenia (PMID: 23794683). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 113 of the GFPT1 protein (p.Asp113Gly).
