Elevated maternal homocysteine (Hcy) increases the risk for neural tube defects (NTDs) but how this arises is unclear. Here, the authors show that high levels of Hcy on histone H3K79Hcy correlate with NTDs, causing abnormal gene expression (for example Cecr2, Smarca4 and Dnmt3B) linked to neural tube closure.
