Researchers find gene that makes some infants susceptible to respiratory and gastrointestinal illness

Editor(s): .

New research published in October 2018 has discovered that multiple genetic variants within the FUT2 gene make some infants especially susceptible to respiratory and gastrointestinal illness.  The UK-based study genotyped DNA samples from over 1,800 mother and baby pairs for two FUT2 polymorphisms, screening for incidences of diarrhea and respiratory problems over a two-year period. 

The researchers concluded that infants who possessed the FUT2 G allele were more likely to experience vomiting, diarrhea, pneumonia/bronchitis or nocturnal coughing than infants possessing the FUT2 A allele.
