MARS1

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.

Compound heterozygous changes in the MARS1 gene were identified in a UDN participant with global developmental delay, eye and vision abnormalities, and gastrointestinal dysmotility.

Date of Report

Jun 10, 2025

Full Name

Methionyl-TRNA Synthetase 1

Location

Chromosome 12 (12q13.3)

Function

This gene encodes for a protein that plays an important role in protein biosynthesis as a component of the multi-tRNA synthetase complex and it catalyzes ligation of methionine to tRNA molecules [provided by RefSeq, Jan 2011].
