Summaries for 3-Methylcrotonyl-Coa Carboxylase 2 Deficiency

UniProtKB/Swiss-Prot : 75 3-methylcrotonoyl-CoA carboxylase 2 deficiency: An autosomal recessive disorder of leucine catabolism. The phenotype is variable, ranging from neonatal onset with severe neurological involvement to asymptomatic adults. There is a characteristic organic aciduria with massive excretion of 3-hydroxyisovaleric acid and 3- methylcrotonylglycine, usually in combination with a severe secondary carnitine deficiency.

MalaCards based summary : 3-Methylcrotonyl-Coa Carboxylase 2 Deficiency, also known as 3-methylcrotonyl coa carboxylase 2 deficiency, is related to 3 alpha methylcrotonyl-coa carboxylase 2 deficiency, and has symptoms including lethargy, seizures and vomiting. An important gene associated with 3-Methylcrotonyl-Coa Carboxylase 2 Deficiency is MCCC2 (Methylcrotonoyl-CoA Carboxylase 2).
