  • Identification of 28 new susceptibility loci for type 2 diabetes in the Japanese population. - Nature genetics (2019) · Suzuki K, Akiyama M, Ishigaki K, Kanai M, Hosoe J, Shojima N, Hozawa A, Kadota A, Kuriki K, Naito M, Tanno K, Ishigaki Y, Hirata M, Matsuda K, Iwata N, Ikeda M, Sawada N, Yamaji T, Iwasaki M, Ikegawa S, Maeda S, Murakami Y, Wakai K, Tsugane S, Sasaki M, Yamamoto M, Okada Y, Kubo M, Kamatani Y, Horikoshi M, Yamauchi T, Kadowaki T · PubMed 30718926

    To understand the genetics of type 2 diabetes in people of Japanese ancestry, we conducted A meta-analysis of four genome-wide association studies (GWAS; 36,614 cases and 155,150 controls of Japanese ancestry). We identified 88 type 2 diabetes-associated loci (P < 5.0 × 10 ) with 115 independent signals (P < 5.0 × 10 ), of which 28 loci with 30 signals were novel. Twenty-eight missense variants were in linkage disequilibrium (r > 0.6) with the lead variants. Among the 28 missense variants, three previously unreported variants had distinct minor allele frequency (MAF) spectra between people of Japanese and European ancestry (MAF > 0.05 versus MAF < 0.01), including missense variants in genes related to pancreatic acinar cells (GP2) and insulin secretion (GLP1R).

Lifestyle context

Concrete actions anchored to the cited research. We do not prescribe, we describe.

Diet

  • Low glycemic index dietary pattern Moderate

    Diets emphasizing low glycemic index foods reduce postprandial glucose spikes in type 2 diabetes

    Emphasize whole grains, legumes, fiber; limit refined carbohydrates and sugary beverages

Discuss with your doctor

  • Type 2 diabetes genetic risk and personalized prevention strategy High

    Genetic risk variants should be contextualized with modifiable risk factors and family history in personalized care planning

Exercise

  • Regular moderate-intensity aerobic exercise Moderate

    Physical activity improves insulin sensitivity and glucose metabolism in genetically predisposed individuals

    150 minutes per week of moderate-intensity aerobic activity such as brisk walking

Lifestyle

  • Maintain healthy body weight Moderate

    Excess body weight amplifies the metabolic effects of type 2 diabetes genetic risk variants

    Maintain BMI 18.5-24.9; aim for 5-10% weight loss if currently overweight

Screening

  • Type 2 diabetes screening with HbA1c and fasting glucose Moderate

    Increased genetic predisposition to type 2 diabetes warrants proactive monitoring for glucose dysregulation

    HbA1c and fasting glucose every 1-2 years starting at age 30; annually if BMI >25
