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.

Ambry Genetics

Mar 25, 2024

The c.2378G>A (p.R793H) alteration is located in exon 15 (coding exon 15) of the CHERP gene. This alteration results from a G to A substitution at nucleotide position 2378, causing the arginine (R) at amino acid position 793 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
