Genes affected

CPNE7 (HGNC:2320): (copine 7) This gene encodes a member of the copine family, which is composed of calcium-dependent membrane-binding proteins. The gene product contains two N-terminal C2 domains and one von Willebrand factor A domain. The encoded protein may be involved in membrane trafficking. Two alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2008]

The c.839C>T (p.P280L) alteration is located in exon 8 (coding exon 8) of the CPNE7 gene. This alteration results from a C to T substitution at nucleotide position 839, causing the proline (P) at amino acid position 280 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
