Involvement in diseasei

Methylmalonyl-CoA epimerase deficiency (MCEED) [MIM:251120]: Autosomal recessive inborn error of amino acid metabolism, involving valine, threonine, isoleucine and methionine. This organic aciduria may present in the neonatal period with life-threatening metabolic acidosis, hyperammonemia, feeding difficulties, pancytopenia and coma.1 Publication
Note: The disease is caused by mutations affecting the gene represented in this entry.
