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.115C>A (p.L39M) alteration is located in exon 3 (coding exon 1) of the EPN2 gene. This alteration results from a C to A substitution at nucleotide position 115, causing the leucine (L) at amino acid position 39 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
