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 this gene was identified in a female, age 3, with facial differences, heart abnormalities (hypoplastic left heart syndrome, mitral regurgitation, aortic insufficiency), kidney abnormalities (vesicoureteral reflux, hydronephrosis, medullary nephrocalcinosis), and global developmental delay (read full description).

Full Name

ankyrin repeat domain 44

Chromosome 2 (2q33.1)


ANKRD44 codes for an ankyrin repeat protein, which is a subunit of the protein phosphatase 6 (PP6). PP6 plays a role in the cell cycle, DNA damage repair, inflammatory signaling and lymphocyte development (Stefansson et al., 2008; Ohama, 2019).
