An extremely rare disorder of methionine cycle and sulfur amino acid metabolism characterized by increased urine excretion of beta-mercaptolactate-cysteine disulfide (due to deficiency of mercaptopyruvate sulfurtransferase activity in erythrocytes), leading to a positive cyanide nitroprusside test. Association with intellectual disability, congenital lens dislocation, and behavioral abnormalities has been reported, however the causal link remains to be established. There have been no further descriptions in the literature since 1981. |

A rare inborn error of metabolism characterized by cabbage-like breath odor with high levels of methanethiol and dimethylsulfide in oral and nasal breath, due to methanethiol oxidase deficiency. Laboratory examination shows elevated levels of dimethylsulfide, dimethylsulfoxide, and dimethylsulfone in blood, cerebrospinal fluid (CSF), and urine. |

Additional clinical features may include heart defects. |
