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 threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 27 of the SLC34A1 protein (p.Thr27Met). This variant is present in population databases (rs139640340, gnomAD 0.006%). This missense change has been observed in individual(s) with clinical features of SLC34A1-related conditions (PMID: 33964006). 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: "Benign"; 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. -
