Variant 15-65003169-G-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_139242.4(MTFMT):c.1063C>G(p.Gln355Glu) variant causes a missense change. The variant allele was found at a frequency of 0.00000274 in 1,461,446 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. Q355Q) has been classified as Benign.

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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on MTFMT protein function. ClinVar contains an entry for this variant (Variation ID: 1492324). This variant has not been reported in the literature in individuals affected with MTFMT-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces glutamine, which is neutral and polar, with glutamic acid, which is acidic and polar, at codon 355 of the MTFMT protein (p.Gln355Glu). -
