Genes affected

ATP2A3 (HGNC:813): (ATPase sarcoplasmic/endoplasmic reticulum Ca2+ transporting 3) This gene encodes one of the SERCA Ca(2+)-ATPases, which are intracellular pumps located in the sarcoplasmic or endoplasmic reticula of muscle cells. This enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen, and is involved in calcium sequestration associated with muscular excitation and contraction. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

The c.2890G>A (p.G964R) alteration is located in exon 20 (coding exon 20) of the ATP2A3 gene. This alteration results from a G to A substitution at nucleotide position 2890, causing the glycine (G) at amino acid position 964 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
