Genes affected

CHERP (HGNC:16930): (calcium homeostasis endoplasmic reticulum protein) Enables transmembrane transporter binding activity. Involved in positive regulation of calcineurin-NFAT signaling cascade and release of sequestered calcium ion into cytosol. Acts upstream of or within cellular calcium ion homeostasis and negative regulation of cell population proliferation. Located in perinuclear region of cytoplasm.

The c.2177G>A (p.R726K) alteration is located in exon 13 (coding exon 13) of the CHERP gene. This alteration results from a G to A substitution at nucleotide position 2177, causing the arginine (R) at amino acid position 726 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
