Abstract Cystathionine beta‐synthase‐deficient homocystinuria (HCU) is a life‐threatening disorder of sulfur metabolism. HCU can be treated by using betaine to lower tissue and plasma levels of homocysteine (Hcy). Here, we show that mice with severely elevated Hcy and potentially deficient in the …
