On this page, you will find information about a genetic change that was identified in a UDN participant. 

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 CDIPT gene were identified in a male, age 4, with seizures, involuntary muscle contractions (dystonia), global developmental delay, and upbeat nystagmus (read full description).

Full Name

CDP-diacylglycerol--inositol 3-phosphatidyltransferase

Chromosome 16 (16p11.2)


Also known as phosphatidylinositol synthase, this protein is a member of the CDP-alcohol phosphatidyl transferase class-I family, and is an integral membrane protein located on the cytoplasmic side of the endoplasmic reticulum and the Golgi apparatus. It functions to catalyze the biosynthesis of phosphatidylinositol (Lykidis et al., 1997).
