Genes affected

CPNE2 (HGNC:2315): (copine 2) Calcium-dependent membrane-binding proteins may regulate molecular events at the interface of the cell membrane and cytoplasm. This gene is one of several genes that encode a calcium-dependent protein containing two N-terminal type II C2 domains and an integrin A domain-like sequence in the C-terminus. Sequence analysis identified multiple alternatively spliced transcript variants but their full-length natures could not be determined. [provided by RefSeq, Jul 2008]

Ambry Genetics

May 30, 2023

The c.23G>T (p.G8V) alteration is located in exon 2 (coding exon 1) of the CPNE2 gene. This alteration results from a G to T substitution at nucleotide position 23, causing the glycine (G) at amino acid position 8 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
