Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3
The NM_032634.4(PIGO):c.2168C>T(p.Ser723Leu) variant causes a missense change. The variant allele was found at a frequency of 0.00000496 in 1,611,918 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 (★★). Synonymous variant affecting the same amino acid position (i.e. S723S) has been classified as Likely benign.

Hyperphosphatasia with intellectual disability syndrome 2 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 01, 2022 | This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 723 of the PIGO protein (p.Ser723Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PIGO-related conditions. ClinVar contains an entry for this variant (Variation ID: 540455). 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. - |
