Labcorp Genetics (formerly Invitae), Labcorp RCV001068660 SCV001233785 uncertain significance Hereditary motor and sensory neuropathy, Okinawa type; Hereditary spastic paraplegia 57 2023-04-26 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 TFG protein function. ClinVar contains an entry for this variant (Variation ID: 862024). This variant has not been reported in the literature in individuals affected with TFG-related conditions. This variant is present in population databases (rs548772203, gnomAD 0.03%). This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 385 of the TFG protein (p.Arg385Cys). 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 RCV002348473 SCV002619697 uncertain significance Inborn genetic diseases 2024-04-22 criteria provided, single submitter clinical testing The c.1153C>T (p.R385C) alteration is located in exon 8 (coding exon 7) of the TFG gene. This alteration results from a C to T substitution at nucleotide position 1153, causing the arginine (R) at amino acid position 385 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
