This article discusses potential indications for genetic testing in an African American patient with chronic kidney disease who is being evaluated for a kidney transplant. Two known risk variants in the APOL1 (apolipoprotein L1) gene predispose to kidney disease and are found almost exclusively in persons of African ancestry. APOL1 risk variants are considered, including whether clinicians should incorporate genetic testing in the screening process for living kidney donors. In addition to APOL1 testing, the role of diagnostic exome sequencing in evaluating potential transplant recipients and donors with a positive family history of kidney disease is discussed.
本文讨论了一名非裔美国慢性肾脏病患者接受肾脏移植评估时基因检测的潜在适应证。APOL1(载脂蛋白 L1)基因中的两个已知风险变异与肾脏病易感性相关,且几乎仅存在于非裔人群中。讨论了 APOL1 风险变异的相关内容,包括临床医生是否应将基因检测纳入活体肾脏供者筛选过程。除了 APOL1 检测,还讨论了外显子组测序在具有肾脏病阳性家族史的潜在移植受者和供者评估中的作用。
