Invitae RCV001939652 SCV002231345 pathogenic not provided 2023-12-15 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 426 of the ALPL protein (p.Gly426Ser). This variant is present in population databases (rs770548228, gnomAD 0.003%). This missense change has been observed in individuals with autosomal dominant and autosomal recessive hypophosphatasia (PMID: 24276437, 28401263, 29236161). This variant is also known as G409S. ClinVar contains an entry for this variant (Variation ID: 1455042). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt ALPL protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects ALPL function (PMID: 28000043). For these reasons, this variant has been classified as Pathogenic.
