l-2-Hydroxyglutaric aciduria (l-2-HGA) is characterized by progressive deterioration of central nervous system function including epilepsy and macrocephaly in 50% of cases, and elevated levels of l-2-hydroxyglutaric acid in urine, blood and cerebrospinal fluid (CSF). Nuclear magnetic resonance imaging shows distinct abnormalities. We report the identification of a gene for l-2-HGA aciduria (MIM 236792) using homozygosity mapping. Nine homozygous mutations including three missense mutations, two nonsense mutations, two splice site mutations and two deletions were identified in the gene C14orf160, localized on chromosome 14q22.1, in 21 patients from one non-consanguineous and 14 consanguineous Turkish families. We propose to name the gene duranin. Duranin encodes a putative mitochondrial protein with homology to FAD-dependent oxidoreductases. The functional role of this enzyme in intermediary metabolism in humans remains to be established.

Multiple acyl-CoA dehydrogenation deficiency is genetically heterogenous metabolic disease with mutations in genes involved in electron transfer to the mitochondrial respiratory chain. Disease symptoms vary from severe neonatal form to late-onset presentation with metabolic acidosis, lethargy, vomiting, muscle pain and weakness. Riboflavin therapy has been shown to ameliorate diseases symptoms in some of these patients. Recently, mutations in FAD synthase have been described to cause multiple acyl-CoA dehydrogenation deficiency. We describe here the effect of riboflavin supplementation therapy in a previously reported adult patient with multiple acyl-CoA dehydrogenation deficiency having compound heterozygous gene variations in FLAD1 (MIM: 610595) encoding FAD synthase. We present thorough clinical history including laboratory investigations, muscle MRI, muscle biopsy and spiroergometric analyses comprising of a follow-up of 20 years. Our data suggest that patients with adult-onset multiple acyl-CoA dehydrogenation deficiency with FLAD1 gene mutations also benefit from long-term riboflavin therapy.
