BACKGROUND: The SMOOTHING BALM TO STREIGHTEN AND PROTECT availability of direct-to-consumer personalized genetic testing has enabled the public to access and interpret their own genetic information.Various genetic traits can be determined including resistance to norovirus through a nonsense mutation (G428A) in the FUT2 gene.Although this trait is believed to confer resistance 10-inch to the most dominant norovirus genotype (GII.4), the spectrum of resistance to other norovirus strains is unknown.
The present report describes a cluster of symptomatic norovirus GI.6 infection in a family identified to have norovirus resistance through personalized genetic testing.
