Transient neonatal diabetes mellitus and activating mutation in the KCNJ11 gene in two siblings.

Summary Transient neonatal diabetes mellitus is a rare disease usually associated with chromosome 6 abnormalities. Mutations of the genes encoding the potassium channel are rarely associated with these transitional forms. Herein, we report the clinical features of two siblings with a heterozygous mutation C679 G>A in the KCNJ11 gene. [ABSTRACT FROM AUTHOR]
