Genetic Screening May Predict Risk of CMV Infection

Researchers have found that the protein nucleotide-binding oligomerization domain 1 (NOD1) is involved in regulating cytomegalovirus (CMV) infection and that loss-of-function NOD1 variants may result in higher susceptibility to CMV infection, which can lead to devastating developmental defects in fetuses and severe disease in people with weakened immune systems.
