Resistance to norovirus infections
Noroviruses are RNA viruses of the Caliciviridae family, and are also called “Norwalk-like” viruses. This virus causes approximately 90% of non-bacterial epidemic outbreaks of gastroenteritis around the world. Norovirus affects people of all ages. About 20% of the population is resistant to most norovirus infections. Such individuals are called non-secretors. Several polymorphisms in the FUT2 gene are associated with non-secretor status and resistance to norovirus infection.
Indications for genetic testing:
1. Determination of resistance status to infection by the most common type of norovirus
