Genetic Study Links GDF15 Gene to Severe Pregnancy Nausea and Type 2 Diabetes Risk
A recent genetic study has identified the gene for growth differentiation factor 15 (GDF15) as a significant cause of hyperemesis gravidarum (HG), a severe form of nausea and vomiting during pregnancy. The study, published in Nature Genetics, is the largest of its kind and highlights GDF15 as a primary genetic risk factor for HG. The research also discovered six additional genes associated with the condition, including one linked to glucagon-like peptide-1 (GPL-1), a hormone involved in insulin regulation and appetite. This gene is also a known risk factor for type 2 diabetes. The findings could lead to new treatment options for HG, which currently lacks FDA-approved treatments. The study involved data from over 11,000 individuals with HG and more than 420,000 without the condition, primarily of European descent, but also included diverse populations.
