WebAug 26, 2024 · Classical homocystinuria (HCU) is an autosomal recessive disorder caused by a deficiency in cystathionine β-synthase (CBS) that results in a defect in the catabolic pathway of the amino acid methionine. CBS is a pyridoxine (vitamin-B6) dependent enzyme that is responsible for the conversion of homocysteine to cystathionine. WebHowever, the biochemical mechanism underlying homocystinuria is not yet fully explained. Some hypotheses include: defects in fibril disulfide bridges as a basis for lens dislocation, or the deficiency in cystathionine-b-synthase could affect the nutritional metabolism of the lens zonule, causing its degeneration and rupture.
