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.

de novo change in the MAMDC4 gene was identified in a UDN participant with behavioral disorders, congenital heart defects, and a brain malformation.

Date of Report

Jun 05, 2023

Full Name

Zinc Finger Protein 169

Chromosome 9 (9q22.32)


The function of ZNF169 is not well described. It is believed to be involved in enabling DNA-binding transcription repressor activity and negative regulation of transcription by RNA polymerase II (Alliance of Genome Resources, 2022).
