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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.1421T>A (p.V474E) alteration is located in exon 10 (coding exon 8) of the EPN2 gene. This alteration results from a T to A substitution at nucleotide position 1421, causing the valine (V) at amino acid position 474 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
