Multiple Mitochondrial Dysfunctions Syndrome 5; Mmds5


MMDS5 is an autosomal recessive disorder characterized mainly by progressive neurologic deterioration beginning in early infancy. Affected individuals have essentially no psychomotor development and have early-onset seizures with neurologic decline and spasticity. Brain imaging shows severe leukodystrophy with evidence of dys- or delayed myelination. Death usually occurs in early childhood (summary by Shukla et al., 2017).For a general description and a discussion of genetic heterogeneity of multiple mitochondrial dysfunctions syndrome, see MMDS1 (OMIM ).
