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.

Feb 05, 2024

The c.1563G>C (p.K521N) alteration is located in exon 16 (coding exon 15) of the CPNE4 gene. This alteration results from a G to C substitution at nucleotide position 1563, causing the lysine (K) at amino acid position 521 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
