Genes affected

CPNE4 (HGNC:2317): (copine 4) This gene belongs to the highly conserved copine family. It encodes a calcium-dependent, phospholipid-binding protein, which may be involved in membrane trafficking, mitogenesis and development. Alternative splicing results in multiple transcript variants.

Ambry Genetics

Sep 27, 2022

The c.275G>A (p.R92Q) alteration is located in exon 3 (coding exon 2) of the CPNE4 gene. This alteration results from a G to A substitution at nucleotide position 275, causing the arginine (R) at amino acid position 92 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
