Genes affected
SLC8A3 (HGNC:11070): (solute carrier family 8 member A3) This gene encodes a member of the sodium/calcium exchanger integral membrane protein family. Na+/Ca2+ exchange proteins are involved in maintaining Ca2+ homeostasis in a wide variety of cell types. The protein is regulated by intracellular calcium ions and is found in both the plasma membrane and intracellular organellar membranes, where exchange of Na+ for Ca2+ occurs in an electrogenic manner. Alternative splicing has been observed for this gene and multiple variants have been described. [provided by RefSeq, Aug 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2022The c.2140G>A (p.E714K) alteration is located in exon 7 (coding exon 6) of the SLC8A3 gene. This alteration results from a G to A substitution at nucleotide position 2140, causing the glutamic acid (E) at amino acid position 714 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
