*Eastbio*: Decoding the genetics of cognitive functions
University of St Andrews
Dr Silvia Paracchini
Deadline: 16th December 2021
How did human cognitive abilities evolve? What are the genes involved in cognition? Are different cognitive functions, such as language and mathematical abilities, controlled by the same mechanisms? Answering these questions is very challenging, but unprecedented resources have allowed initial and highly promising discoveries in this field. Large cohorts characterised with a wide range of cognitive traits and genomic data are now available, and reference datasets that provide multiple layers of functional annotations for the human genome are constantly growing. By using this type of data, our recent genome-wide association study (GWAS) for language abilities pinpointed specific genomic regions which tended to show signatures of recent and rapid evolution in humans. The same language-associated regions are also regulating the expression of genes during neurodevelopment.
Building on these findings, the present project will investigate specific research questions with a range of computational approaches. GWAS for different cognitive abilities, e.g. memory and maths skills will identify specific genetic variants and genomic regions and allow follow-up analyses. For example, comparative genomics will assess whether the regions associated with cognitive abilities overlap with ultra-conserved or rapidly evolving sequences. The results will show whether cognitive abilities evolved via similar mechanisms or whether the pattern identified for language is distinctively unique. As observed for most human traits, the associated genetic variants are likely to influence gene expression regulation. GWAS analysis will be integrated with high quality reference gene expression and epigenetic datasets derived from different tissues and different cell types. These data will allow us to test whether the variants associated with cognitive traits have a functional effect in specific cells or brain regions.
All data required by the project have already been generated and are immediately available. Training will be provided by three experienced supervisors (Silvia Paracchini, Sonja Vernes and Andy Lynch) who have established track records for the approaches required for the success of this project. Their leading roles in international consortia will provide access to large data resources as well as opportunities to further develop new lines of investigation.
If you want to address big questions, learn cutting-edge computational methods, and work as part of multidisciplinary and international teams, then this is the ideal project for you.
