 Human Rare Diseases 
Classical homocystinuria

 Gene Information 
Gene Name Cbs
Old Gene Names for Cbs Ai047524 , Ai303044
Gene Description cystathionine beta-synthase [Source:MGI Symbol;Acc:MGI:88285]
MGI phenotype Homozygous targeted mutants are severely growth retarded and die within 5 weeks of birth with enlarged multinucleate hepatocytes filled with lipid and massively elevated plasma homocysteine levels. Heterozygotes have twice normal homocysteine levels, but survive and breed.
