Figure 2. Pedigrees of Families with Hypoglycaemia.

Patients with hypoglycaemia are shaded with bold diagonal stripes; patients who had hypoglycaemia but have progressed onto diabetes are shaded with half black/half diagonal stripes; and patients with diabetes are coloured black. Probands are indicated with an arrow. Where available, below each symbol is recorded genotype (NM, HNF4A-mutation carrier; NN, unaffected), birth centile adjusted for sex and gestation, age at which diabetes developed, and the patient's treatment.
