SUCLA2-related mitochondrial DNA depletion syndrome

Variants (also called mutations) in the SUCLA2 gene cause SUCLA2-related mtDNA depletion syndrome, an inherited disorder that affects the early development of the brain. SUCLA2 gene variants alter the structure of the beta subunit of succinyl-CoA ligase, reducing the enzyme's activity. 

A shortage (deficiency) of normal succinyl-CoA ligase leads to problems with the production and maintenance of mtDNA, particularly in the developing brain and muscles. A reduction in the amount of mtDNA (known as mtDNA depletion) impairs energy production within cells. These problems lead to weak muscle tone (hypotonia), delayed development, and the other characteristic features of SUCLA2-related mtDNA depletion syndrome.
