Genes affected

CPNE6 (HGNC:2319): (copine 6) This gene encodes a member of the copine family. Members of this family are calcium-dependent, phospholipid-binding proteins with C2 domains, two calcium- and phospholipid-binding domains. Through their domain structure and lipid binding capabilities, these proteins may play a role in membrane trafficking. This protein is thought to be brain-specific and has a domain structure of two N-terminal C2 domains and one von Willebrand factor A domain. It may have a role in synaptic plasticity.

The c.1222G>A (p.G408S) alteration is located in exon 14 (coding exon 13) of the CPNE6 gene. This alteration results from a G to A substitution at nucleotide position 1222, causing the glycine (G) at amino acid position 408 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
