About
Hugh-Owen Colhoun is a leading researcher in the field of inborn errors of metabolism, with a particular focus on galactosaemia and its long-term complications. His work has fundamentally advanced our understanding of the biochemical underpinnings of classical galactosaemia, a rare but serious genetic disorder. Colhoun’s most notable contribution is his 2016 study, "Classical galactosaemia: novel insights in IgG N-glycosylation and N-glycan biosynthesis," which has garnered 46 citations. This seminal paper revealed that patients with galactosaemia exhibit distinct abnormalities in immunoglobulin G (IgG) glycosylation, providing the first clear evidence that the disease disrupts N-glycan biosynthesis beyond the well-known galactose metabolism pathway. This discovery has opened new avenues for understanding the pathophysiology of long-term complications such as cognitive impairment and ovarian failure. Colhoun’s work is highly regarded for its translational impact, bridging basic glycobiology with clinical metabolic disease. His research continues to shape diagnostic and therapeutic strategies, making him a pivotal figure in the metabolic disease community.
