Pathogenic variants in 11 genes (ABCC8, KCNJ11, CNOT1, EIF2AK3, SLC19A2, IER3IP1, PTF1A, NEUROD1, MNX1, WFS1, and NKX2-2) are known to cause neonatal diabetes with neurological features, ranging from developmental delay to structural abnormalities such as microcephaly (3, 4). The gene discussed is EIF2AK3; the disease is microcephaly.
