Clinical relevance (Genomics England PanelApp)

Diagnostic Grade (Green)

  • Hypophosphataemia or rickets

    BIALLELIC, autosomal or pseudoautosomal
  • Nephrocalcinosis or nephrolithiasis

  • Fetal anomalies

    BIALLELIC, autosomal or pseudoautosomal
  • Osteogenesis imperfecta

  • Renal tubulopathies

    BIALLELIC, autosomal or pseudoautosomal

Score is the Open Targets composite evidence score (0-1). Higher = stronger gene-disease association.

Protein function (UniProt)

Sodium-dependent phosphate transport protein 2C

Involved in actively transporting phosphate into cells via Na(+) cotransport in the renal brush border membrane (PubMed:11880379). The cotransport has a Na(+):Pi stoichiometry of 2:1 and is electroneutral (By similarity)
