On this page, you will find information about genetic changes that were 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.

Changes in the PAPSS1 gene were identified in a female, age 10, with global developmental delay, severe motor impairment, involuntary muscle contractions (dystonia), and increase in activated immune cells (recurrent hemophagocytic lymphohistiocytosis (HLH)) (read full description).
