On this page, you will find information about genetic changes that were 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.

Changes in this gene were identified in two UDN participants with developmental delay and abnormal MRI findings (T2 hyperintensity of caudate nuclei and putamen bilaterally) (read full description).

Date of Report

Feb 13, 2018

Full Name

Mitochondrial trans-2-enoyl-CoA reductase

Chromosome 1 (1p35.3)


The MECR gene codes for a protein involved in mitochondrial fatty acid synthesis (Heimer et. al., 2016).

Clinical Significance

Changes in the MECR gene were identified in two UDN participants with MEPAN syndrome. The MEPAN Foundation, was created to increase awareness and support of this condition.
