Genes affected

CPNE1 (HGNC:2314): (copine 1) Calcium-dependent membrane-binding proteins may regulate molecular events at the interface of the cell membrane and cytoplasm. This gene encodes a calcium-dependent protein that also contains two N-terminal type II C2 domains and an integrin A domain-like sequence in the C-terminus. However, the encoded protein does not contain a predicted signal sequence or transmembrane domains. This protein has a broad tissue distribution and it may function in membrane trafficking. This gene and the gene for RNA binding motif protein 12 overlap at map location 20q11.21. Alternate splicing results in multiple transcript variants encoding different proteins.

Ambry Genetics

Oct 22, 2021

The c.1166G>A (p.R389H) alteration is located in exon 14 (coding exon 14) of the CPNE1 gene. This alteration results from a G to A substitution at nucleotide position 1166, causing the arginine (R) at amino acid position 389 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
