Study on 400,000 individuals finds genes for educational attainment

This study is the second effort coordinated by the Social Science Genetics Association Consortium (SSGAC) to which LIGA contributed data from the Berlin Aging Study II. This newest analysis employed a genome-wide association study (GWAS) approach in 300,000 persons searching for genetic determinants of educational achievement, the largest-ever genetics study in the social sciences. A total of 74 loci were revealed to show genome-wide significant association with years of schooling. The identified loci were enriched for genomic regions regulating gene expression in the fetal brain. The study was published in the journal Nature.

Three new genes identified for subjective well-being

This study was coordinated by the Social Science Genetics Association Consortium (SSGAC) of which our group is a member via contributing data from the Berlin Aging Study II. In total, our study investigated the data of nearly 300,000 individuals searching for genetic determinants of subjective well-being, depressive symptoms, and neuroticism. Using a genome-wide association study (GWAS) approach, we identified 16 signals associated with one of more of the investigated phenotypes. Pinpointed loci tended to be involved in regulating gene expression in the central nervous system and adrenal or pancreas tissues. The study was published in the journal Nature Genetics.

Novel guidelines for preclinical Alzheimer’s disease

Our group has participated in a recent effort to formulate novel recommendations about the definitions, the limits, the natural history, the markers of progression, and the ethical consequence of detecting Alzheimer’s disease at its preclinical, asymptomatic stage. This work is the result of a workshop held by the International Working Group (IWG) and the American Alzheimer’s Association on “The Preclinical State of AD” on July 23, 2015; Washington DC, USA. The guidelines were recently published in the journal Alzheimer’s & Dementia.
