Genes affected

EPN2 (HGNC:18639): (epsin 2) This gene encodes a protein which interacts with clathrin and adaptor-related protein complex 2, alpha 1 subunit. The protein is found in a brain-derived clathrin-coated vesicle fraction and localizes to the peri-Golgi region and the cell periphery. The protein is thought to be involved in clathrin-mediated endocytosis. Alternate splicing of this gene results in multiple transcript variants encoding different isoforms.

The c.1133C>T (p.P378L) alteration is located in exon 7 (coding exon 5) of the EPN2 gene. This alteration results from a C to T substitution at nucleotide position 1133, causing the proline (P) at amino acid position 378 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
