Transient neonatal diabetes mellitus (TNDM) is associated with paternal over-expression of an imprinted locus on chromosome 6q24, which contains one differentially methylated region (DMR); maternal demethylation at the DMR accounts for approximately 20% of cases. Here we report female monozygous triplets, two of whom have TNDM arising from loss of maternal methylation within the TNDM DMR.
短暂性新生儿糖尿病(TNDM)与6号染色体6q24上一个印记位点的父源过表达相关,该位点包含一个差异甲基化区域(DMR);约20%的病例是由DMR处的母源去甲基化引起的。在此,我们报告了女性单卵三胞胎,其中两个患有TNDM,病因是TNDM DMR内母源甲基化缺失。
