Genes affected

SLC34A3 (HGNC:20305): (solute carrier family 34 member 3) This gene encodes a member of SLC34A transporter family of proteins, and is expressed primarily in the kidney. It is involved in transporting phosphate into cells via sodium cotransport in the renal brush border membrane, and contributes to the maintenance of inorganic phosphate concentration in the kidney. Mutations in this gene are associated with hereditary hypophosphatemic rickets with hypercalciuria. Alternatively spliced transcript variants varying in the 5' UTR have been found for this gene.[provided by RefSeq, Apr 2010]

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. This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 261 of the SLC34A3 protein (p.Ser261Gly). This variant is present in population databases (rs201964796, gnomAD 0.2%). This variant has not been reported in the literature in individuals affected with SLC34A3-related conditions. ClinVar contains an entry for this variant (Variation ID: 436755). 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 not expected to disrupt SLC34A3 protein function. -
