TLDR  A woman experienced severe side effects from a drug due to a specific genetic variation, suggesting genetic testing could prevent such risks.   
  This case report described a 37-year-old woman who experienced azathioprine-induced agranulocytosis and severe alopecia after a kidney transplant, which was linked to a NUDT15 polymorphism (rs116855232, p.Arg139Cys). The patient had stable renal function post-transplant and was on a triple-immunosuppressant regimen. The NUDT15 polymorphism was identified through genome-wide correlation analysis, marking this as the first reported case of such adverse effects in a kidney transplant patient with this genetic variant.
