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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2022The c.596C>T (p.S199L) alteration is located in exon 4 (coding exon 2) of the EPN2 gene. This alteration results from a C to T substitution at nucleotide position 596, causing the serine (S) at amino acid position 199 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
