WebFeb 9, 2024 · Cystathionine beta-synthase deficiency [CBS] syndrome or classical homocystinuria is a multisystem disorder caused by the deficiency of CBS, an enzyme in the transsulfuration pathway of homocysteine metabolism. It was first described in 1960 as a variant of Marfan syndrome. The true population frequency is unknown, with estimates … WebThe gene underlying this phenotype was found to encode a protein containing a putative membrane-localized domain of unknown function (DUF21) and a cystathionine-β-synthase domain. The cbs1 mutants had defective infection threads that were sometimes devoid of rhizobia and formed small nodules with greatly reduced numbers of symbiosomes.
