SUCLG1 Antibody

1. We report two Tunisian patients belonging to a consanguineous family with mitochondrial encephalomyopathy. Mutational analysis of SUCLG1 gene showed the presence of c.41T > C in exon 1 in a homozygous state. This mutation substitutes a conserved methionine residue to a threonine at position 14 (p.M14T) located at the SUCLG1 protein mitochondrial targeting sequence. PMID: 29217198
2. These abnormal phenotypes are rescued upon ectopic expression of wild-type SUCLG1 in the patient's fibroblasts, thus functionally confirming the pathogenic nature of the SUCLG1 VUS identified in this patient and expanding the phenotypic spectrum for SUCLG1 deficiency PMID: 27484306
3. Long survival, to age 20 years or older, was reported in 12% of SUCLA2 and in 10% of SUCLG1 patients. PMID: 26475597
4. First Chinese report of succinyl-CoA ligase deficiency caused by novel SUCLG1 mutations; five novel pathogenic mutations in SUCLG1 were identified PMID: 26028457
5. 3 novel mutations have been identified in patients with the mitochondrial DNA depletion syndrome (c.1048G>A and c.1049G>T in SUCLA2 and c.531+4A>T in SUCLG1). PMID: 22980518
6. Our results suggest that SUCLG1 mutations that lead to complete absence of SUCLG1 protein are responsible for a very severe disorder with antenatal manifestations, whereas a SUCLA2-like phenotype is found in patients with residual SUCLG1 protein. PMID: 20693550
7. This report enlarges the phenotypic spectrum of SUCLG1 mutations and confirms that a characteristic metabolic profile (presence of MMA and C4-DC carnitine in urines) and basal ganglia MRI lesions are the hallmarks of SCS defects. PMID: 20197121
8. A novel mutation in the SUCLG1 gene was found in two newborns having lethal lactic acidosis, multi-organ failure and congenital malformations including interrupted aortic arch. PMID: 20227526
