Biomarker of autosomal dominant polycystic kidney disease; chronic kidney disease (multiple); hyperthyroidism; hypophosphatemia; and hypothyroidism. Human ortholog(s) of this gene implicated in several diseases, including Fanconi syndrome (multiple); chronic kidney disease; hereditary hypophosphatemic rickets with hypercalciuria; hypophosphatemic nephrolithiasis/osteoporosis 1; and nephrolithiasis. Orthologous to human SLC34A1 (solute carrier family 34 member 1). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
