Curiously, SNPs in EBF1 have been identified [32] that even link to cases of Anorexia Nervosa (AN), with Fretz et al. having pointed out years earlier that the phenotype of many patients with AN—which often feature elevated levels of bone adiposity [39,40]—essentially phenocopies that of the Ebf1−/− animals [5]. This evidence concerns the gene EBF1 and anorexia nervosa.
