Infant gut microbiome development and type 1 diabetes risk

A prospective, longitudinal analysis of the developing gut microbiome in infants en route to type 1 diabetes

Longitudinal stool samples (N=124) from 33 infants in Finland and Estonia, recruited at birth based on HLA risk genotyping. Tracked monthly for three years to characterize microbiome changes preceding type 1 diabetes seroconversion and onset. machine-written summary

Archive description

This is a prospective, longitudinal collection of stool samples from infants at risk for disease. Infants from Finland and Estonia were recruited at birth based on HLA risk genotyping. Parents collected their infants’ stool at approximately monthly intervals and promptly stored the sample in the freezer prior to shipment for sample processing and sequencing. The cohort comprised of 33 infants, 11 of which seroconverted to serum autoantibody positivity and of those, four developed T1D within the three year time-frame of this study.
