Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The NM_014861.4(ATP2C2):​c.2319G>C​(p.Gly773Gly) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. G773G) has been classified as Benign.

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.
