Genes affected
CPNE3 (HGNC:2316): (copine 3) Calcium-dependent membrane-binding proteins may regulate molecular events at the interface of the cell membrane and cytoplasm. This gene encodes a protein which contains two type II C2 domains in the amino-terminus and an A domain-like sequence in the carboxy-terminus. The A domain mediates interactions between integrins and extracellular ligands. [provided by RefSeq, Aug 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 19, 2021The c.102T>A (p.F34L) alteration is located in exon 3 (coding exon 1) of the CPNE3 gene. This alteration results from a T to A substitution at nucleotide position 102, causing the phenylalanine (F) at amino acid position 34 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
