| Outline of Final Research Achievements |
Genetic factors play very important roles in the onset and progression of type 2 diabetes mellitus (T2DM). We reported that copy number losses in the subtelomeric region on chromosome 4p16.3 were detected in early-onset Japanese T2DM patients at a high frequency.
In this study, we found two novel copy number losses within the subtelomeric regions, which have significant associations with early-onset Japanese T2DM. In addition, using the MassArray system, we detected a “one-copy” region in four diabetic patients within the chromosome 4p16.3 region, indicating some genomic alterations in these affected subjects. Furthermore, the 4p16.3 region and whole exomes of 11 diabetic patients was sequenced by the next generation sequencer. Although the big sequencing data are now analyzing, we obtained novel findings which suggest genomic alterations in one allele of several affected subjects.
