Novel Adeno-associated Viral (AAV) Vectors to Treat Hereditary Methylmalonic Acidemia (MMA) Caused by Methylmalonyl-coA Mutase (MMUT) Deficiency

Deficiency of the enzyme in methylmalonyl-CoA mutase (MMUT) results is a life-threatening disease, methylmalonic acidemia (MMA), that carries high rates of morbidity and mortality. NHGRI scientists have developed novel AAV vectors that combine the proprietary codon-optimized synMMUT alleles with either a liver-specific promoter from the human alpha-1...

High Concentration Methylcobalamin (Me-Cbl) or Combination of Methyl- and Hydroxocobalamin (Me/OH-Cbl) for the Treatment of Cobalamin C Deficiency and Related Disorders

Cobalamin C deficiency (cblC), caused by mutations in MMACHC, is the most common inborn error of intracellular vitamin B12 metabolism. NHGRI scientist have generated a number of Mmachc knockout mouse models. The cblC mice present with early lethality, recapitulate the neurological phenotype seen in patients, and have enabled proof of concept testing...

Gene Therapy for Cobalamin C Deficiency (cblC) with Viable Mouse Models

Cobalamin C deficiency (cblC) is the most common inborn error of intracellular cobalamin metabolism and is caused by mutations in MMACHC, a gene responsible for processing and trafficking dependent enzymes: intracellular cobalamin, resulting in elevated methylmalonic acid and homocysteine and methionine deficiency. Disease manifestations include growth...

Modulating Autophagy as a Treatment for Lysosomal Storage Diseases

Researchers at NIAMS have developed a technology for treatment of lysosomal storage diseases by inhibition of autophagy. Pompe disease is an example of a genetic lysosomal storage disease caused by a reduction or absence of acid alpha-glucosidase (GAA). Patients with Pompe disease have a lysosomal buildup of glycogen in cardiac and skeletal muscle...
