Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 153 of the SLC34A1 protein (p.Gly153Ala). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This missense change has been observed in individual(s) with infantile hypercalcemia (PMID: 26047794). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 234930). 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 SLC34A1 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects SLC34A1 function (PMID: 26047794). For these reasons, this variant has been classified as Pathogenic.
