Role of MYH9 and APOL1 in African and non-African populations with lupus nephritis

Abstract

Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by autoantibody production and organ damage. Lupus nephritis (LN) is one of the most severe manifestations of SLE. Multiple studies reported associations between renal diseases and variants in the non-muscle myosin heavy chain 9 (MYH9) and the neighboring apolipoprotein L 1 (APOL1) genes. We evaluated 167 variants spanning MYH9 for association with LN in a multiethnic sample. The two previously identified risk variants in APOL1 were also tested for association with LN in European-Americans (EAs) (N = 579) and African-Americans (AAs) (N = 407). Multiple peaks of association exceeding a Bonferroni corrected P-value of P < 2.03 × 10(-3) were observed between LN and MYH9 in EAs (N = 4620), with the most pronounced association at rs2157257 (P = 4.7 × 10(-4), odds ratio (OR) = 1.205). A modest effect with MYH9 was also detected in Gullah (rs8136069, P = 0.0019, OR = 2.304). No association between LN and MYH9 was found in AAs, Asians, Amerindians or Hispanics. This study provides the first investigation of MYH9 in LN in non-Africans and of APOL1 in LN in any population, and presents novel insight into the potential role of MYH9 in LN in EAs.

Figures

Figure 1
Figure 1. Summary of association analysis for MYH9 SNPs
Plots of SNPs within the MYH9 gene associated with lupus nephritis in (a) European American, (b) African American and (c) Gullah populations. Genotyped SNPs are represented by circles and imputed SNPs are shown in rectangles. The recombination rate calculated from the combined CEU, YRI and JPT + CHB Hapmap data is denoted by the purple solid line. The dotted line refers to the Bonferroni threshold of significance.

This plot shows the pair-wise LD between all markers given in the figure. SNPs in red box represent Effect 1 and SNPs in green box represent Effect 2. The intensities of the LD between SNPs are depicted in orange (Effect 1), green (Effect 2), and black (between Effect 1 and Effect 2).
