Genes affected

CPNE5 (HGNC:2318): (copine 5) 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. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene. More variants may exist, but their full-length natures could not be determined.

Ambry Genetics

Jan 17, 2023

The c.1270C>T (p.R424C) alteration is located in exon 17 (coding exon 17) of the CPNE5 gene. This alteration results from a C to T substitution at nucleotide position 1270, causing the arginine (R) at amino acid position 424 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
