Genes affected

SLC20A1 (HGNC:10946): (solute carrier family 20 member 1) The protein encoded by this gene is a sodium-phosphate symporter that absorbs phosphate from interstitial fluid for use in cellular functions such as metabolism, signal transduction, and nucleic acid and lipid synthesis. The encoded protein is also a retroviral receptor, causing human cells to be susceptible to infection by gibbon ape leukemia virus, simian sarcoma-associated virus, feline leukemia virus subgroup B, and 10A1 murine leukemia virus.[provided by RefSeq, Mar 2011]

Sep 12, 2023

The c.674A>G (p.K225R) alteration is located in exon 6 (coding exon 5) of the SLC20A1 gene. This alteration results from a A to G substitution at nucleotide position 674, causing the lysine (K) at amino acid position 225 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
