Figure 4

Development and validation of allele-specific qPCR primers for APOL1 variant detection. Top panel: Illustration of standard “unmodified” or custom-designed “modified” primer sequences for the SNP-1 (A), SNP-2 (B) and deletion (C) loci. Altered or deleted base pairs are demarcated by dotted lines. Bottom panel: Quantitative analysis of qPCR data illustrates homozygous or heterozygous variants. 2–0: homozygous WT, 1–1: heterozygous, 0–2: homozygous SNP/deletion (N: number of bases remaining in the primer sequence).
