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 PHACTR1 gene was identified in a 13-year-old female with unsteady gait (gait ataxia), intellectual disability, absent speech, and seizures (read full description).

Date of Report

Full Name

phosphatase and actin regulator 1

Chromosome 6 (6p24.1)


PHACTR1 encodes a protein that regulates cell morphology and movement. This protein has an important role in brain development, especially in forming synapses and neuronal migration (Hamada et al., 2018).
