UGT1A1 and neonatal jaundice: The missense variant was consistently fine-mapped as one of the variants with the largest probability of driving the association with UGT1A1 expression in the colon and neonatal jaundice (posterior probability > 0.10, Supplementary Fig. 7), with an opposite effect direction (increase of UGT1A1 expression lowers risk of neonatal jaundice).
