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 KMT2C gene was identified in a male, age 18 with global developmental delay, autism, severe nearsightedness (myopia), different facial features, and a history of heart defects (atrial septal defect, ventricular septal defect), and cleft palate (read full description).

Date of Report

Full Name

lysine methyltransferase 2C

Chromosome 7 (7q36.1)


The KMT2C gene encodes for a histone methyltransferase that modifies chromatin structure and regulates gene transcription through mediation of mono- and tri-methylation of histone H3 at lysine 4 (Koemans et al., 2017).
