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 ZNF331 gene was identified in a UDN participant global developmental delay, decreased muscle tone (hypotonia), delayed brain development (delayed myelination), visual impairment, and a large head size (macrocephaly) (read full description).

Date of Report

Feb 07, 2023

Full Name

Zinc finger protein 331

Chromosome 19 (19q13.42)


ZNF331 gene may play a role in spermatogenesis (Wu et al., 2001). This gene encodes a zinc finger protein containing a KRAB (Kruppel-associated box) domain which plays a role in transcription (Sobocinska et al., 2021).
