Sixteen new genes for reproductive behavior in humans

This work represents the first bona-fide genome-wide association study (GWAS) assessing reproductive behavior in humans, to which LIGA contributed the data from the Berlin Aging Study II. Overall, nearly 350,000 individuals were analyzed leading to the identification of 16 independent loci that are significantly associated with ‘age at first birth’ and/or ‘number of children ever born’. These identified loci harbor genes that are likely to have a role,in human reproduction and infertility. The study was published in the journal Nature Genetics.

GxE study on inflammation and air polution in PD

Both air pollution exposure and systemic inflammation have been linked to Parkinson’s disease (PD). In this study, led by long-time LIGA collaborator Prof. Beate Ritz at UCLA in the USA, we correlated long term traffic related air pollution measures with genetic markers for inflammation. The analyses showed suggestive evidence that a combination of traffic-related air pollution and genetic variation in the IL1B gene may contribute to risk of developing PD. The results were published in the journal Environmental Research.

First genome-wide GxE study in PD published

The LIGA team was part of a collaborative effort where we performed the first ever genome-wide gene-environment interaction (GxE) analysis of pesticide exposure and risk of Parkinson’s disease (PD). The results of this effort suggest that the effect of pesticide exposure on PD risk may be modified by SNPs in the ERCC6L2 gene. This finding needs to be replicated in independent samples before it should be considered as established. The results were published in the journal Parkinsonism and Related Disorders.

Announcement of MDSGene

Investigators from LIGA and the Institute of Neurogenetics today announced their upcoming launch of MDSGene, the Movement Disorders Society Genetics database. MDSGene aims to provide a comprehensive, systematic overview of published data on movement disorder patients reported to carry causative gene mutations. The official launch of the resource will happen during the 20th Congress of the International Movement Disorders Society which takes place in Berlin between June 19-23. After AlzGene, ALSGene, and PDGene, MDSGene (which will become available at www.mdsgene.org) represents the fourth genetics database developed by the LIGA team. The launch announcement was published as an editorial by members of the MDSGene team in the journal Movement Disorders.
