Genes affected

ATP2C2 (HGNC:29103): (ATPase secretory pathway Ca2+ transporting 2) Enables P-type calcium transporter activity and P-type manganese transporter activity. Predicted to be involved in calcium ion transmembrane transport; cellular calcium ion homeostasis; and manganese ion transport. Predicted to act upstream of or within mammary gland epithelium development; positive regulation of calcium ion import; and protein localization to plasma membrane. Predicted to be located in trans-Golgi network membrane. Predicted to be active in Golgi membrane; endoplasmic reticulum; and plasma membrane. Predicted to be integral component of membrane.

Collection Method:clinical testing

The c.8A>G (p.E3G) alteration is located in exon 1 (coding exon 1) of the ATP2C2 gene. This alteration results from a A to G substitution at nucleotide position 8, causing the glutamic acid (E) at amino acid position 3 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
