We analyse large-scale genetic and electronic health record data from populations in which parental relatedness (consanguinity) is common, to explore fine-scale structure, its impact on disease risk, and the genetic architecture of both rare and complex diseases.
Elena Arciero and Mari Niemi will be joining the group soon as postdocs. We are advertising for another postdoc in statistical genetics. Please contact Hilary (hcm at sanger.ac.uk) if you would like to discuss.
We are starting new and exciting projects using data from large cohorts of individuals enriched for parental relatedness, includingn East London Genes and Health (currently N~30,000 British South Asians), Born in Bradford (N=12,000, ~half with Pakistani ancestry), and Deciphering Developmental Disorders (N=10,000 trios, mixed ancestries).
The group will investigate such questions as:
- Does autozygosity impact complex traits, and if so, through which types of variation?
- How does autozygosity contribute to rare disorders beyond simple monogenic recessive inheritance?
- How can individuals with consanguinity help us to learn more about incomplete/variable penetrance?
- How does the biraderi (clan) structure in Pakistani populations impact the distribution of disease-causing variation?
- Which genes are under recessive selection, and can we leverage this to inform discovery of disease genes?
- How do current and historical patterns of consanguinity differ between populations?
A key feature of our work is to work in partnership with the individuals and populations we are studying. We uphold strict data security and confidentiality procedures and work closely with cohorts we are studying in community engagement and dissemination of our scientific findings.
