Green List (high evidence)

Comment on list classification: There is enough evidence to rate this gene as Green at the next GMS panel update - sufficient number of unrelated cases (>3) supported by a NFU1 deficiency rat model which exhibited PAH.

Biallelic variants in this gene cause multiple mitochondrial dysfunctions syndrome, a severe neonatal onset disorder of systemic energy metabolism, resulting in weakness, respiratory failure, lack of neurologic development, leukodystrophy, lactic acidosis, and early death.

More than 50% of infant patients are found to display significant PAH, which can initially be an isolated and prominent finding (PMID: 22077971; 25918518; 28470589; 31516295; 32669393). Pulmonary samples from NFU1-deficient individuals with PAH showed obstructive vasculopathy with proximal and acinar arterial involvement (PMID: 22077971).

Humanised rare model of NFU1 deficiency showed features of mitochondrial dysfunction comparable to those observed in patients and also developed PAH (PMID: 31461310)
