In particular, we identify two new subgroups of interest: (i) a subgroup of diabetics characterized by the consumption of insulin, directly linked to type-I diabetes (by remarking that none ICD9-CM code for this specific kind of diabetes was used during training); and (ii) a cluster of pregnant women who presented complications during pregnancy, including hypertension and gestational diabetes. The gene discussed is INS; the disease is type 1 diabetes mellitus.
