In three non-syndromic NDM cases (one incident, two past patients) we did not find any variant in the MDG of the panel or in the new NDM genes ONECUT1 and ZNF808. Among these 3, two presented with diabetes beyond six months and before 1 year (cases 66, 68) and were classified as early-onset antibody-negative T1D (Table 4). Here, ONECUT1 is linked to neonatal diabetes mellitus.
