Inborn genetic diseases Uncertain:1
The c.1123C>G (p.P375A) alteration is located in exon 8 (coding exon 7) of the TFG gene. This alteration results from a C to G substitution at nucleotide position 1123, causing the proline (P) at amino acid position 375 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not provided Uncertain:1
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis indicates that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Hereditary motor and sensory neuropathy, Okinawa type;C3714897:Hereditary spastic paraplegia 57 Uncertain:1
This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 375 of the TFG protein (p.Pro375Ala). This variant is present in population databases (no rsID available, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with TFG-related conditions. ClinVar contains an entry for this variant (Variation ID: 534742). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt TFG 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. -
