Genes affected
SLC34A1 (HGNC:11019): (solute carrier family 34 member 1) Enables sodium:phosphate symporter activity. Involved in several processes, including phosphate ion homeostasis; phosphate ion transport; and response to lead ion. Located in several cellular components, including apical plasma membrane; mitotic spindle; and nuclear speck. Implicated in several diseases, including Fanconi syndrome (multiple); chronic kidney disease; hereditary hypophosphatemic rickets with hypercalciuria; hypophosphatemic nephrolithiasis/osteoporosis 1; and nephrolithiasis.

This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 179 of the SLC34A1 protein (p.Leu179Pro). This variant is present in population databases (rs142772770, gnomAD 0.006%). This missense change has been observed in individual(s) with nephrocalcinosis (PMID: 28893421). ClinVar contains an entry for this variant (Variation ID: 548680). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. -
