In a male proband with transient neonatal diabetes (TNDM3; 610582), Gloyn et al. (2005) identified a heterozygous G-to-C transversion in the KCNJ11 gene, resulting in a gly53-to-arg (G53R) substitution. The mutation was not identified in 100 control individuals. The proband had insulin-treated diabetes diagnosed at age 16 weeks and went into remission by 17 months with relapse at age 28 months. The affected mother was positive for the mutation and was diagnosed with diabetes at 11 weeks with no periods of remission. Both mother and son had learning difficulties. In transformed Xenopus oocytes, the G53R mutation resulted in a reduction in sensitivity to ATP when compared with wildtype; however, the effect was less than that of PNDM-associated mutations.
