A mechanism observed in other species as well
However, Michel Georges' team investigated further. Pursuing the study using bioinformatic approaches, the team identified polymorphisms (common mutations) among humans and mice that are likely to act in the same way as they do in the Texel breed. It appears, therefore, that this new kind of mutation, discovered while studying sheep, could contribute significantly to the phenotypic variation observed in many species – among which humans – including the hereditary predisposition to various diseases.
Researchers at ULg have thus produced a database available online that compiles all these mutations (the Patrocles database: http://www.patrocles.org). It will assist researchers around the world in discovering similar phenomena for other phenotypes including hereditary diseases.
