Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1PM2PP2PP3_StrongPP5
The NM_001040716.2(PC):c.788G>A(p.Arg263Gln) variant causes a missense change. The variant allele was found at a frequency of 0.00000274 in 1,461,424 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 Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. R263R) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 31, 2021 | This sequence change replaces arginine with glutamine at codon 263 of the PC protein (p.Arg263Gln). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and glutamine. This variant is present in population databases (rs769177104, ExAC 0.006%). This variant has not been reported in the literature in individuals affected with PC-related conditions. ClinVar contains an entry for this variant (Variation ID: 203921). 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"). 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. - |
