Genes affected

SLC24A3 (HGNC:10977): (solute carrier family 24 member 3) Plasma membrane sodium/calcium exchangers are an important component of intracellular calcium homeostasis and electrical conduction. Potassium-dependent sodium/calcium exchangers such as SLC24A3 are believed to transport 1 intracellular calcium and 1 potassium ion in exchange for 4 extracellular sodium ions (Kraev et al., 2001 [PubMed 11294880]).[supplied by OMIM, Mar 2008]

The c.826G>A (p.V276I) alteration is located in exon 10 (coding exon 10) of the SLC24A3 gene. This alteration results from a G to A substitution at nucleotide position 826, causing the valine (V) at amino acid position 276 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
