Genetic diversity of NDUFV1-dependent mitochondrial complex I deficiency.

ABSTRACT: Medical genomics research performed in diverse population facilitates a better understanding of the genetic basis of developmental disorders, with regional implications for community genetics. Autosomal recessive mitochondrial complex I deficiency (MCID) accounts for a constellation of clinical features, including encephalopathies, myopathies, and Leigh Syndrome. Using whole-exome sequencing, we identified biallelic missense variants in NDUFV1 that encodes the 51-kD subunit of complex I (NADH dehydrogenase) NDUFV1. Mapping the variants on published crystal structures of mitochondrial complex I demonstrate that the novel c.1118T > C (p.(Phe373Ser)) variant is predicted to diminish the affinity of the active pocket of NDUFV1 for FMN that correlates to an early onset of debilitating MCID symp
