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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.293G>A (p.C98Y) alteration is located in exon 4 (coding exon 2) of the CPNE3 gene. This alteration results from a G to A substitution at nucleotide position 293, causing the cysteine (C) at amino acid position 98 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
