Sarah Leigh (Genomics England Curator)

Comment on list classification: Associated with relevant phenotype in OMIM, but not associated with phenotype in Gen2Phen. At least 1 variant reported in a 12.5-year old girl, born of Turkish parents who were likely distantly related, with mitochondrial complex I deficiency. The proband died from cardiorespiratory failure associated with infection and metabolic crisis at 12.5 years. No further variants reported to date (30/09/2019).

Ellen McDonagh (Genomics England Curator)

Comment on list classification: As this is reported in a single case, this should be a red gene until further evidence arises.
