On this page, you will find information about a genetic change that was identified in a UDN participant. We are trying to find others with the same or similar condition.

Sharing information on this website is not a requirement of UDN participation. Only descriptions about participants who give explicit consent will appear here.

A change in the PEX19 gene was identified in a male, age 10, with seizures, structural brain abnormalities, and global developmental delay (read full description).

Date of Report

Mar 07, 2022

Full Name

Peroxisomal Biogenesis Factor 19

Chromosome 1 (1q23.2)


The PEX19 gene encodes for a protein that interacts with peroxisomal membrane proteins (PMP), whose function is not entirely understood. The PEX19 protein is thought to act as a chaperone protein in refolding misfolded PMP proteins, play a role in inserting PMP proteins in the cell membrane, and assist in the creation of peroxisomes (Emmanouilidis, et al., 2017).
