Cystathionin test
WebCystathionine is a dipeptide which is then converted to cysteine using the enzyme cystathionine gamma- lyase (CTH). Currently, there is no known source or physiologic function for cystathionine other than serving as a transsulfuration intermediate. WebSummary. Homocystinuria caused by cystathionine β-synthase (CBS) deficiency is characterized by involvement of the eye (ectopia lentis and/or severe myopia), skeletal system (excessive height, long limbs, scolioisis, and pectus excavatum), vascular system (thromboembolism), and CNS (developmental delay/intellectual disability).
