| Invitae | RCV001225711 | SCV001397998 | uncertain significance | Hereditary motor and sensory neuropathy, Okinawa type; Hereditary spastic paraplegia 57 | 2022-12-23 | 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. 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 TFG protein function. ClinVar contains an entry for this variant (Variation ID: 953420). This variant has not been reported in the literature in individuals affected with TFG-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 137 of the TFG protein (p.Glu137Gln). |
