Özet

Objectives Neonatal diabetes mellitus (NDM) is a rare form of monogenic diabetes present within the first six months of life. NDM can be transient (TNdM) or permanent (PNDM). About 70% of TNDM cases have abnormalities in the imprinted region of chromosome 6q24. In TNDM, diabetes remits at infancy whilst may relapse later in life. Chromosome 6q24 related TNDM usually relapses at the pubertal period, while in some cases, relapse occurs earlier. It has been reported that these cases can respond to sulfonylurea treatment, while more evidence and experience are needed. Case presentation Herein, we reported relapse of diabetes at prepubertal age and its response to sulphonylurea therapy in a case with TNDM due to a homozygous c.7734C>T (p.R228C) variant in the ZFP57 gene. Conclusions A response to the sulphonylurea monotherapy seems not optimal for relapsed TNDM due to chromosome 6q24 abnormalities.
