Genes affected

CPNE2 (HGNC:2315): (copine 2) Calcium-dependent membrane-binding proteins may regulate molecular events at the interface of the cell membrane and cytoplasm. This gene is one of several genes that encode a calcium-dependent protein containing two N-terminal type II C2 domains and an integrin A domain-like sequence in the C-terminus. Sequence analysis identified multiple alternatively spliced transcript variants but their full-length natures could not be determined. [provided by RefSeq, Jul 2008]

The c.575T>A (p.L192Q) alteration is located in exon 6 (coding exon 5) of the CPNE2 gene. This alteration results from a T to A substitution at nucleotide position 575, causing the leucine (L) at amino acid position 192 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
