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 GeneticsSep 24, 2024The c.2116A>G (p.I706V) alteration is located in exon 6 (coding exon 5) of the SLC8A3 gene. This alteration results from a A to G substitution at nucleotide position 2116, causing the isoleucine (I) at amino acid position 706 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
