ATAD3A

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 ATAD3A gene was identified in a male, who passed away at 19 months, with poor growth, small head (severe progressive microcephaly), global developmental delay, vision and hearing impairment, autoimmune disease, and brain abnormalities (read full description).

Full Name

ATPase Family AAA Domain Containing 3A

Location

Chromosome 1 (1p36.33)

Function

The ATAD3A gene encodes for a mitochondrial membrane protein that is involved in many critical cellular processes such as mitochondrial dynamics, cell death, and cholesterol metabolism (Teng, et al., 2019). This gene has been associated with Harel-Yoon syndrome (OMIM: 617183) and with neonatal lethal pontocerebellar hypoplasia, hypotonia, and respiratory insufficiency syndrome (OMIM: 618810).
