Novel GNB1 Mutations Disrupt Assembly and Function of G Protein Heterotrimers and Cause Global Developmental Delay in Humans
Global developmental delay (GDD), often accompanied by intellectual disability, seizures and other features is a severe, clinically and genetically highly heterogeneous childhood-onset disorder. In cases where genetic causes have been identified, de-novo mutations in neuronally expressed genes are…

Identification of a Novel Deletion in the MMAA Gene in Two Iranian Siblings with Vitamin B12-Responsive Methylmalonic Acidemia
Adenosylcobalamin (vitamin B12) is a coenzyme required for the activity of methylmalonyl-CoA mutase. Defects in this enzyme are a cause of methylmalonic acidemia (MMA). Methylmalonic acidemia, cblA type, is an inborn error of vitamin B12 metabolism that occurs due to mutations in the MMAA gene. MMAA…

Molecular, Biochemical, and Structural Analysis of a Novel Mutation in Patients with Methylmalonyl-CoA Mutase Deficiency
Methylmalonic aciduria (MMA) is an inborn error of metabolism resulting from genetic defects in methylmalonyl-CoA mutase (MCM). We found one homozygous nucleotide change in intron 12 of the MUT gene (c.2125-3 C > G).
