Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PM1PM2PM5PP3_StrongPP5_Very_Strong
The NM_000137.4(FAH):c.1027G>A(p.Gly343Arg) 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 Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G343W) has been classified as Likely pathogenic.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Nov 16, 2019 | For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Gly343 amino acid residue in FAH. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 12203990, 21764616). 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has been observed in individual(s) with tyrosinemia (PMID: 23927806). ClinVar contains an entry for this variant (Variation ID: 558592). This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with arginine at codon 343 of the FAH protein (p.Gly343Arg). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and arginine. - |
