Cystathionine beta-synthase p.S466L mutation causes hyperhomocysteinemia in mice.

Abstract excerpt

Missense mutations in the cystathionine beta-synthase (CBS) gene are the most common cause of clinical homocystinuria in humans. The p.S466L mutation was identified in a homocystinuric patient, but enzymatic studies with recombinant protein show this mutant to be highly active. To understand how this mutation causes disease in vivo, we have created mice lacking endogenous mouse CBS and expressing either wild-type...
