Why rare disease research isn't just about rare diseases

18 November 2013 - by Oliver Timmis

The idea of a rare disease informing wider knowledge about fundamentals of biology is now well established.

Gene variant may explain increased flu severity among Chinese

04 February 2013 - by Matthew Thomas

A genetic variant frequently found in Chinese populations may explain why severe complications from swine flu are more common in China. The discovery may also have implications for other influenza virus strains and help scientists understand why flu outbreaks hit some populations harder than others.... [Read More]

'Marry out?' Some surprising consequences of genetic disease risk among Ashkenazi Jews

28 May 2012 - by Dr Jessica Mozersky

Ashkenazi Jews have historically been an endogamous population. Marrying within the group remains important to many Jews because endogamy is seen as one way to preserve Judaism and ensure the survival of future generations.
