Genes affected

SLC5A8 (HGNC:19119): (solute carrier family 5 member 8) SLC5A8 has been shown to transport iodide by a passive mechanism (Rodriguez et al., 2002 [PubMed 12107270]) and monocarboxylates and short-chain fatty acids by a sodium-coupled mechanism (Gopal et al., 2004 [PubMed 15322102]). In kidney, SLC5A8 functions as a high-affinity sodium-coupled lactate transporter involved in reabsorption of lactate and maintenance of blood lactate levels (Thangaraju et al., 2006 [PubMed 16873376]).[supplied by OMIM, Dec 2008]

The c.1433A>C (p.Q478P) alteration is located in exon 12 (coding exon 12) of the SLC5A8 gene. This alteration results from a A to C substitution at nucleotide position 1433, causing the glutamine (Q) at amino acid position 478 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
