Review for Region: ISCA-37442-Gain was set to GREEN
Added comment: Transient neonatal diabetes mellitus-1 (TNDM1; '6q diabetes') is caused by overexpression of the paternal allele of the imprinted locus at chromosome 6q24, which contains PLAGL1.

Three genetic mechanisms had been shown to result in TNDM: paternal uniparental isodisomy of chromosome 6, paternally inherited duplication of 6q24, and a methylation defect at a CpG island overlapping exon 1 of ZAC/HYMAI (promoter of PLAGL1). Note that over 50% of individuals with TND and hypomethylation at 6q24 also show mosaic DNA hypomethylation at other imprinted loci throughout the genome and a range of additional clinical features.
