? Better pathway for analysis - mitoAR mitochondrial complex 1 defic - nuclear type 14. Berger et al, 2008 - 3 consang families of Israeli-Bedouin origin in which 6 offspring had severe mito complex 1 defic. 3 of the aff children presented with a fatal infantile metabolic acidosis with death between 6-40 days. Aff children in 1 family survived beyond infancy but deverloped severe encephalocardiomyopathy with brain atrophy, no motor development and HCM. Hom splice variant identified in all - paper mentions 1 child had a convulsive disorder appear at 4 months of age. No mention on OMIM of an epilepsy phenotype.Created: 6 Aug 2019, 8:31 p.m. | Last Modified: 6 Aug 2019, 8:31 p.m.

Comment on list classification: Based on single case and the observation that not all the carriers manifested with convulsive disorderCreated: 6 Dec 2018, 4:14 p.m.
Comment when marking as ready: Associated with phenotype in OMIM and not in Gen2Phen. At least one homozygous variant identified in a large consanguineous Bedoin family, convulsive disorder appeared at 4 months in one patient (PMID 18306244).Created: 6 Dec 2018, 4:13 p.m.
