Genes affected

CPNE3 (HGNC:2316): (copine 3) Calcium-dependent membrane-binding proteins may regulate molecular events at the interface of the cell membrane and cytoplasm. This gene encodes a protein which contains two type II C2 domains in the amino-terminus and an A domain-like sequence in the carboxy-terminus. The A domain mediates interactions between integrins and extracellular ligands. [provided by RefSeq, Aug 2008]

Feb 12, 2024

The c.338G>A (p.R113Q) alteration is located in exon 5 (coding exon 3) of the CPNE3 gene. This alteration results from a G to A substitution at nucleotide position 338, causing the arginine (R) at amino acid position 113 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
