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 GeneticsJun 16, 2023The c.307G>A (p.E103K) alteration is located in exon 3 (coding exon 3) of the SLC24A3 gene. This alteration results from a G to A substitution at nucleotide position 307, causing the glutamic acid (E) at amino acid position 103 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
