Here we report a novel mutation in OPA3 (320-337del) in a Kurdish-Turkish patient with optic atrophy and 3-methylglutaconic and 3-methylglutaric aciduria, previously carrying the diagnosis of type IV MGA.
Depending on the clinical and biochemical phenotype we suggest POLG1, SUCLA2, TMEM70 and RYR1 sequence analysis and mtDNA-depletion studies in children with 3-methylglutaconic aciduria type IV.

In the light of recent reports linking cases of type IV 3-methylglutaconic aciduria (3-MGCA) and hypertrophic cardiomyopathy to mutations in TMEM70, we proceeded with sequencing analysis of this gene.
