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.290A>G (p.H97R) alteration is located in exon 2 (coding exon 2) of the CPNE7 gene. This alteration results from a A to G substitution at nucleotide position 290, causing the histidine (H) at amino acid position 97 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
