JAMA Study Reveals 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 from three institutions, led by investigators at Vanderbilt University Medical Center, provide an example of how using genetic data could reduce a health disparity. 

“We’ve essentially created this racial health disparity by not fully considering how genetic variation affects white blood cell levels,” said Jonathan Mosley, MD, PhD, Assistant Professor of Medicine and Biomedical Informatics at VUMC. “Our study supports genotyping African Americans before performing a bone marrow biopsy for the indication of isolated low white blood cell counts.”
