Neonatal Diabetes Mellitus: Novel Mutations.

The authors describe 5 novel mutations, in the EIF2AK3, ABCC8, and GCK genes, a homozygous mutation at the ABCC8 locus presenting as TNDM, an obscure phenotype of the GCK gene mutation, and hyperglycemia-induced hemichorea-hemiballismus in a patient with TRMA. In India, PNDM is most commonly due to WRS similar to Middle Eastern countries with high consanguinity rates.
