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]

The c.950A>G (p.N317S) alteration is located in exon 12 (coding exon 10) of the CPNE3 gene. This alteration results from a A to G substitution at nucleotide position 950, causing the asparagine (N) at amino acid position 317 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
