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.664G>A (p.A222T) alteration is located in exon 6 (coding exon 6) of the CPNE7 gene. This alteration results from a G to A substitution at nucleotide position 664, causing the alanine (A) at amino acid position 222 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
