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

Feb 21, 2024

The c.12G>A (p.M4I) alteration is located in exon 2 (coding exon 1) of the CPNE4 gene. This alteration results from a G to A substitution at nucleotide position 12, causing the methionine (M) at amino acid position 4 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
