Publication Open Access The body mass index increases the genetic risk scores' ability to predict risk of hepatic damage in European adolescents: the HELENA study(Wiley, 2023) Seral-Cortes, Miguel; Sabroso-Lasa, Sergio; González Gross, Marcela; Quesada-González, Carlos; Stehle, Peter; Gottrand, Frédéric; Marcos, Ascensión; Diaz, Ligia Esperanza; Manios, Yannis; Androutsos, Odysseas; Widhalm, Kurt; Molnár, Dénes; Huybrechts, Inge; Muntaner, Manon; Meirhaeghe, Aline; Salazar-Tortosa, Diego; Ruiz, Jonatan R.; Esteban, Luis Mariano; Labayen Goñi, Idoia; Moreno, Luis A.; Ciencias de la Salud; Osasun ZientziakBackground: Hepatic disorders are often complex and multifactorial, modulated by genetic and environmental determinants. During the last years, the hepatic disease has been progressively established from early stages in life. The use of genetic risk scores (GRS) to predict the genetic susceptibility to a particular phenotype among youth has gained interest in recent years. Moreover, the alanine aminotransferase (ALT) blood biomarker is often considered as hepatic screening tool, in combination with imaging techniques. The aim of the present study was to develop an ALT-specific GRS to help in the evaluation of hepatic damage risk in European adolescents. Methods: A total of 972 adolescents (51.3% females), aged 12.5¿17.5 years, from the Healthy Lifestyle in Europe by Nutrition in Adolescence study were included in the analyses. The sample incorporated adolescents in all body mass index (BMI) categories and was divided considering healthy/unhealthy ALT levels, using sex-specific cut-off points. From 1212 a priori ALT-related single nucleotide polymorphisms (SNPs) extracted from candidate gene selection, a first screening of 234 SNPs univariately associated was established, selecting seven significant SNPs (p <.05) in the multivariate model. An unweighted GRS (uGRS) was developed by summing the number of reference alleles, and a weighted GRS (wGRS), by multiplying each allele to its estimated coefficient. Results: The uGRS and wGRS were significantly associated with ALT (p <.001). The area under curve was obtained integrating BMI as clinical factor, improving the predictive ability for uGRS (.7039) and wGRS (.7035), using 10-fold internal cross-validation. Conclusions: Considering BMI status, both GRSs could contribute as complementary tools to help in the early diagnosis of hepatic damage risk in European adolescents.Publication Open Access Single nucleotide polymorphisms of ADIPOQ gene associated with cardiovascular disease risk factors in European adolescents: the HELENA study(Wolters Kluwer, 2020) Salazar-Tortosa, Diego; Pascual Gamarra, José Miguel; Labayen Goñi, Idoia; Rupérez, Azahara I.; Censi, Laura; Béghin, Laurent; Michels, Nathalie; González Gross, Marcela; Manios, Yannis; Lambrinou, Christina-Paulina; Moreno, Luis A.; Meirhaeghe, Aline; Castillo, Manuel J.; Ruiz, Jonatan R.; Ciencias de la Salud; Osasun ZientziakObjectives: Cardiovascular diseases (CVDs) are responsible of 31% of all deaths worldwide. Genetic predisposition to CVDs in adolescents remains largely unknown. Aims of present research are to examine the association of ADIPOQ gene polymorphisms with cardiovascular disease risk factors in European adolescents. Methods: A total of 14 polymorphisms in the ADIPOQ gene were genotyped in 1057 European adolescents (12-18 years old) from the Healthy Lifestyle in Europe by Nutrition in Adolescence Cross-Sectional Study. We measured serum lipids and a CVD risk score, along with weight, height, triceps, and subscapular skinfold thickness, leptin, insulin and other markers of glucose regulation. Results: The rs822393, rs822395 and rs7649121 polymorphisms of ADIPOQ gene were significantly associated with several CVD risk factors [i.e. high-density lipoprotein cholesterol (HDL-C), apolipoprotein (Apo) A1, SBP and CVD risk score] in European adolescents. We also found an association of the TGAAGT ADIPOQ haplotype (rs822393, rs16861210, rs822395, rs822396, rs12495941 and rs7649121) with HDL-C and ApoA1 levels. Conclusion: Several individual polymorphisms (rs822393, rs822395 and rs7649121) and a haplotype of ADIPOQ gene were significantly associated with cardiovascular disease risk factors in European adolescents.
