AbstractA 47-year-old woman was diagnosed with myotonic dystrophy when admitted for traumatic subarachnoid hemorrhage. Her glycemic control was poor despite administration of pioglitazone, a PPARɤ agonist, and subcutaneous insulin infusion. However, adding a GLP-1 receptor (GLP-1R) agonist markedly improved blood glucose levels, resulting in eventual insulin withdrawal. Genetic testing revealed a heterozygous variant, p.R131Q, in the GLP1R (rs3765467), a common variant in Asia. This variant is known to be associated with increased endogenous insulin from beta cells in response to exogenous GLP-1 infusion. This is the first report and short review of a Japanese case of myotonic dystrophy accompanied by GLP-1R gene polymorphism.Copyright © 2024 Southern Society for Clinical Investigation.
