Nicotine GWASThe project is a genome-wide genotyping approach to analyse the genetics of nicotine dependence. We had 1800 samples genotyped for the 900,000 SNPs. In addition to the nicotine addiction, we also worked with Parkinson's disease whole-genome sequencing and RNAseq data from PPMI longitudinal cohort. Thi cohort enables to analyse genetic and lifestyle factors for getting Parkinson's disease.

The main challenges were to identify the genetic associations from the complex data. The aim of the project was to find genetic determinants for nicotine dependence and the smoking connection to complex diseases, like Parkinson’s disease. Data modelling was quite challenging
We applied PLINK for general association analysis using case/control and linear modelling for quantitative data. We used RStudio for more detailed analysis as it is. really flexible for several modelling options
It worked very well. I got sufficient power to perform calculations and do analysis. I am very grateful for PAwsey team helping out with complex installations where I got stuck. Especially with the RStudio. I suggest to set up a server-based R studio version.
