Overview

My laboratory has been working on Huntington's disease (HD) using genetics, bioinformatics, cell and animal models. HD is an inherited disease caused by an expanded repeated section of DNA and the length of the repeat partly determines age-at-onset of disease.  I am particularly interested in genetic modifiers of HD. Genetic variation that modifies disease can be regarded as a therapeutic target since it modifies the disease in people. We showed that DNA repair mechanisms and the exact CAG repeat sequence alter HD age-at-onset and are investigating how this might cause HD in our model systems in the laboratory.

Genetic modifiers in Huntington’s disease

Our latest research just published in Cell (https://www.sciencedirect.com/science/article/pii/S0092867419307391) follows up our first analysis of genetic modifiers in HD from 2015 (GeM-HD http://dx.doi.org/10.1016/j.cell.2015.07.003). Our latest data indicate that not only are pathways involved in DNA handling and repair involved in altering the age at which people get Huntington's disease, but that the sequence of the disease-causing CAG repeat is critical too. Most people - whether or not they have HD - have two copies of a CAG repeat that has a CAACAG hexamer at the 3' end. In a few people though, the repeat has a different sequence at the 3' end: people with expanded CAG repeats with CAACAGCAACAG at the 3' end get Huntington's disease much later than expected, whereas people with no CAA repeat at all, just a pure CAG, get the disease much earlier than expected. This is because the repeat lengths are being measured incorrectly, and it is the pure CAG length rather than the translated HTT protein polyglutamine length that is important, but is also likely due to other factors, potentially related to the structures in the DNA adopted by the repeats of different sequences.

Our motivation in these studies was to identify variation that could delay or precipitate disease onset as the biological pathways that this variation lies in are ideal therapeutic targets, as we know they have this effect in people carrying the mutation. We are extending this study in collaboration with Jim Gusella, Marcy MacDonald, Vanessa Wheeler and Jong-Min Lee (MGH, Boston USA), Seung Kwak (CHDI, USA) and Michael Orth (Ulm University, Germany). I was also the Lead Facilitator of the Genetic Modifiers Working Group (GMWG) of the European Huntington’s Disease Network. I collaborate closely with SarahTabrizi (Institute of Neurology, UCL) and Peter Holmans, in Cardiff to integrate genetic and gene expression data from HD subjects to explore underlying pathology important in disease (10.1093/hmg/ddw142). In collaboration with Sarah Tabrizi, Henry Houlden, Alexandra Durr and other collaborators we also showed that the signal we saw modifying onset in HD modifies onset in a series of spinocerebellar ataxias also caused by repeat expansion mutations (10.1002/ana.24656). This implicates the expansion in the DNA as the main source of modification of the age of onset in these diseases, rather than more downstream events.  We went on to demonstrate that variation in MSH3 on chromosome 5 is associated with how fast HD progresses (.https://doi.org/10.1016/S1474-4422(17)30161-8). We are now exploring how these genes affect HD using cellular and animal models of disease with funding from CHDI, the Dementia Discovery Fund, the Wellcome Trust and the MRC.

Alzheimer’s disease (AD)

I led the work that implicated cholesterol metabolism and innate immune involvement in disease aetiology using pathway analysis (10.1038/mp.2015.23) and the follow up analysis in the International Genomics of Alzheimer's disease Project (IGAP) (https://doi.org/10.1016/j.jalz.2014.05.1757). I have been collborating with Phil Taylor and Paul Morgan in the Systems Immunity University Research Institute to examine the mechanism underlying the immune signal in AD.
