Gene variant linked to unnecessary bone marrow biopsies in African Americans
A gene variant that lowers white blood cell levels and is common in individuals with African ancestry contributes to unnecessary bone marrow biopsies, according to a study published June 28 in JAMA Internal Medicine. The findings, led by investigators at VUMC, are an example of how using genetic data could reduce a health disparity. Read MoreJun 28, 2021
