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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 16, 2023The c.817G>A (p.G273R) 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 817, causing the glycine (G) at amino acid position 273 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
