Objective: To conduct a genome-wide association studies (GWAS) to find genetic variations that affected renal function in the diabetic patients in Japan.

Research design and methods: In a Japanese population of 955 patients with type 2 diabetes mellitus (T2D), extracted from 14,091 participants appropriate for GWAS from the Japan Multi-Institutional Collaborative Cohort (JMICC) study. Genotyping was performed at a central laboratory with use of a HumanOmniExpressExome-8 v1.2 Bead Chip array. Genotype imputation was conducted with use of SHAPEIT, followed by Minimac3 software (with the 1000 Genomes phase 3 as the reference panel). We calculated the estimated glomerular filtration rate (eGFR) for each patient according to Matsuo et al. Association for the imputed variants with eGFR was performed by linear regression analysis with adjustments for age and sex.

Results: We found 77 SNVs upstream of the NBEA genes that were significantly associated with eGFR in T2D participants with P values <5 × 10-8. This gene was reported as participatory in several metabolic functions and was associated with some disease conditions. However, no previous reports implied that the gene was related to nephropathy in diabetes.

Conclusion: We found the 13q35.43-35.46 locus upstream of the NBEA gene was significantly associated with eGFR in participants with T2D in a Japanese population.

Our esteemed journal is looking forward for the upcoming issue (Volume4: Issue1) for the upcoming year as all the authors are invited to submit their recent scientific work through manuscripts in the mode of Research/Case Reports/Case Studies/Reviews/Short Review/ Short Communications/Commentaries/Short Commentaries/Letters to Editor/ Image articles etc.

A standard editorial manager system is utilized for manuscript submission, review, editorial processing and tracking which can be securely accessed by the authors, reviewers and editors for monitoring and tracking the article processing. Manuscripts can be uploaded online at Editorial Tracking System or as email attachment to: clinicaldiabetes@emedicalsci.org
