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 GeneticsJun 02, 2023The c.1928C>A (p.T643N) alteration is located in exon 5 (coding exon 4) of the SLC8A3 gene. This alteration results from a C to A substitution at nucleotide position 1928, causing the threonine (T) at amino acid position 643 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
