CTNNAL1

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 de novo heterozygous change in the CTNNAL1 gene was identified in a UDN participant with heart abnormalities, global developmental delay, brain MRI abnormality, and seizures (infantile spasms) that are now well-treated and controlled (read full description).

Date of Report

Full Name

Catenin Alpha like 1

Location

Chromosome 9 (9q31.3)

Function

The CTNNAL1 gene may be responsible for modulating the Rho pathway signaling by providing a scaffold for the Lbc Rho guanin nucleotide exchange factor (ARHGEF1) (Park et al., 2002).
