These include the writers WTAP and VIRMA, the eraser ALKBH5, and genes encoding reader proteins such as YTHDF1, YTHDF2 and YTHDC1. These results imply a relationship of gene expression with weight and prompted us to further test for a correlation with clinical variables related to obesity. Here, YTHDF1 is linked to obesity due to melanocortin 4 receptor deficiency.
