ALG2

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 ALG2 gene was identified in a male, age 7, with global developmental delay, muscle weakness, hand tremor, increased tone in lower limbs (hypertonia), and facial differences (read full description).
