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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 23, 2023The c.995G>A (p.R332Q) alteration is located in exon 11 (coding exon 10) of the CPNE6 gene. This alteration results from a G to A substitution at nucleotide position 995, causing the arginine (R) at amino acid position 332 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
