Genes affected

ENSG00000304098 (HGNC:):

ENSG00000304098 links:

CTH (HGNC:2501): (cystathionine gamma-lyase) This gene encodes a cytoplasmic enzyme in the trans-sulfuration pathway that converts cystathione derived from methionine into cysteine. Glutathione synthesis in the liver is dependent upon the availability of cysteine. Mutations in this gene cause cystathioninuria. Alternative splicing of this gene results in three transcript variants encoding different isoforms. [provided by RefSeq, Jun 2010]
