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.

The c.2259C>G (p.F753L) alteration is located in exon 23 (coding exon 23) of the ATP2C2 gene. This alteration results from a C to G substitution at nucleotide position 2259, causing the phenylalanine (F) at amino acid position 753 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
