Sexual dimorphism in metabolomic and phenotypic spectra of UGT deficiency: findings from the Canadian Longitudinal Study on Aging.
Article in Biology of sex differences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTwo of the most frequently deleted genes in the human genome are the UDP-glycosyltransferases UGT2B17 and UGT2B28. They encode metabolic enzymes of the glucuronidation pathway that plays a pivotal role in the maintenance of cellular homeostasis for a variety of small molecule metabolites. These deletions may impact health, yet their effects remain poorly understood. We evaluated the impact of UGT deficiency on the plasma metabolome and examined the association between altered metabolites and health outcomes.
methodsThe metabolomic profiles of 4262 proficient gene carriers were compared with those of 352 UGT2B17-deficient, 97 UGT2B28-deficient, and 20 double-gene-deficient individuals from the Canadian Longitudinal Study on Aging. Significant metabolites found in these comparisons were analyzed for their associations with common diseases.
resultsThe unexpectedly broad molecular divergence found in UGT-deficient metabolomes, which affected > 10% of metabolites, implies their significant influence across various metabolite classes-particularly lipids and amino acids - extending beyond their known substrates. The metabolic profiles of UGT2B17-deficient men and UGT2B28-deficient women were most impacted, with UGT2B17 deficiency affecting various metabolites linked to metabolic diseases, arthritis, and osteoporosis. Metabolites impacted by a UGT2B28 deficiency such as amino acids, were linked to metabolic disorders in women.
conclusionThe findings significantly advance our understanding of the metabolic landscape associated with these frequently deleted genes in the human genome, which may influence susceptibility to various diseases in a sex-specific manner, laying the groundwork for determining their pathological mechanisms and impact on human health.
