About

Aim 1:

Determine if there is an association between the APOL1 risk variants and allograft survival and function in African Americans

Determine if there is an association between the presence of APOL1 risk variants in an African American kidney transplant recipient and the risk of recurrent disease

Aim 3:

Investigate mechanisms of APOL1 associated kidney disease by prospectively following African American kidney transplant recipients throughout their clinical course.

Enrollment: 39 patients
