Compositional analysis of genetic ancestry shows that relative proportion of African ancestry is positively associated with fecal myeloperoxidase in Brazilian infants

Josyf C. Mychaleckyj, Alexandre Havt, Uma Nayak…·Aldo Â. M. Lima

The paper shows that higher African ancestry in Brazilian infants is linked to increased fecal myeloperoxidase levels, suggesting genetic factors influence immune response to enteric infections.
