Sarah Leigh (Genomics England Curator)

Comment on list classification: This gene was added as Green due to the overall review and evidence assessment from the GMS mitochondrial specialist test group, submitted by Carl Fratter (May 2019) on behalf of GMS mitochondrial specialist test group: 2 unrelated cases with functional studies.
From panel: Possible mitochondrial disorder - nuclear genes (Version 0.187).

Ivone Leong (Genomics England Curator)

Comment on list classification: Promoted from red to green. This gene is associated with a phenotype in OMIM. PMID: 24119684 describes 2 unrelated patients with different variants in this gene who have mitochondrial disorders. The authors also knocked down this gene in the zebrafish, which caused global mitochondrial and respiratory chain defects. Therefore, there is enough evidence to promote this gene to green.
