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]

Ambry Genetics

Mar 18, 2024

The c.52C>A (p.L18I) alteration is located in exon 3 (coding exon 1) of the CPNE3 gene. This alteration results from a C to A substitution at nucleotide position 52, causing the leucine (L) at amino acid position 18 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
