Overview

This report describes Leigh syndrome, MT-ND2-related, one of several diseases associated with the human mitochondrially-encoded gene MT-ND2. See the human disease model report for mitochondrial complex I deficiency, MT-ND2-related (FBhh0000382) for information on experimental results using Drosophila models of this and related diseases. See MIM:516001 for variants of MT-ND2 associated with Leigh syndrome.

Disease Summary Information
Parent Disease Summary: Leigh syndrome
Symptoms and phenotype

Leigh syndrome is an early-onset progressive neurodegenerative disorder; clinical symptoms depend on which areas of the central nervous system are involved. [from MIM:256000; 2016.01.06]

(OMIM, 2013-)

The symptoms of Leigh syndrome usually begin between the ages of three months and two years. Symptoms are associated with progressive neurological deterioration and may include loss of previously acquired motor skills, loss of appetite, vomiting, irritability, and/or seizure activity. [from NORD, Leigh Syndrome; 2016.08.12]
