Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate
The NM_001127178.3(PIGG):āc.1045A>Gā(p.Arg349Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,764 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā ). Synonymous variant affecting the same amino acid position (i.e. R349R) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 07, 2019 | In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant is present in population databases (rs746477290, ExAC 0.01%) but has not been reported in the literature in individuals with a PIGG-related disease. This sequence change replaces arginine with glycine at codon 349 of the PIGG protein (p.Arg349Gly). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and glycine. - |
