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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2024The c.122A>T (p.K41M) alteration is located in exon 1 (coding exon 1) of the CPNE7 gene. This alteration results from a A to T substitution at nucleotide position 122, causing the lysine (K) at amino acid position 41 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
