A new study says that a gene helps some mothers produce breast milk sugars that are not digested by the infant, but instead nourish specific bacteria that colonize the babies’ guts soon after birth.

The gene, which is not active in some mothers, produces a breast milk sugar called ‘secretors’. Mothers known as ‘non-secretors’ have a non-functional fucosyltransferase 2 (FUT2) gene, which alters the composition of their breast milk sugars and changes how the microbial community, or microbiota, of their infants’ guts develop, the study said.

Senior study author David Mills from the University of California, Davis said that in no way is the nonsecretor mother’s milk less healthy, and their babies are at no greater risk. Mills said that what this work does show us is that the mother’s genotype matters, and that it influences the breast milk, which clearly drives the establishment of microbes in the intestines of their babies.

The research may have applications in a clinical setting for protecting premature infants from a range of intestinal diseases including necrotising enterocolitis (NEC), a condition that is the second most common cause of death among premature infants in the US. The research examined the differences in infant gut microbial populations arising from differences in human milk sugars.

The research was conducted using milk samples from 44 mothers.

The study appeared in the journal Microbiome.
