Variant summary
Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM1PM2PM5PP3_Moderate
The NM_000169.3(GLA):c.868A>G(p.Met290Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M290I) has been classified as Likely pathogenic.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 07, 2021 | 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. This variant disrupts the p.Met290 amino acid residue in GLA. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 29307789, 23935525, 27773586, 28728877, 22773828). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has been observed in individual(s) with Fabry disease (PMID: 27560961). This variant is not present in population databases (ExAC no frequency). This sequence change replaces methionine with valine at codon 290 of the GLA protein (p.Met290Val). The methionine residue is highly conserved and there is a small physicochemical difference between methionine and valine. - |
