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 PRUNE1 gene was identified in a male, age 7, with global developmental delay, hypotonia, muscle spasticity and regression (read full description).

Full Name

prune exopolyphosphatase 1

Chromosome 1 (1q21.3)


PRUNE1 codes for a member of the DHH phosphoesterase family (Reymond et al., 1999). It is highly expressed in the fetal brain and is thought to aid in cell proliferation, migration, and motility by interacting with both signaling and cytoskeleton proteins (Zollo et al., 2017).
