DiseaseDisease

[HMGCL_HUMAN] Defects in HMGCL are the cause of 3-hydroxy-3-methylglutaryl-CoA lyase deficiency (HMGCLD) [MIM:246450]; also known as hydroxymethylglutaricaciduria or HL deficiency. An autosomal recessive disease affecting ketogenesis and L-leucine catabolism. The disease usually appears in the first year of life after a fasting period and its clinical acute symptoms include vomiting, seizures, metabolic acidosis, hypoketotic hypoglycemia and lethargy. These symptoms sometimes progress to coma, with fatal outcome in some cases.[1][2][3][4][5][6][7][8][9][10]

FunctionFunction

[HMGCL_HUMAN] Key enzyme in ketogenesis (ketone body formation). Terminal step in leucine catabolism.[11][12][13]
