Example of a typical REN (A) and AGT (B) threeplex reaction A. The SNaPshot result of a homozygous carrier of the most common REN haplotype, A-G-C (SNP order: rs5705, rs1464816 and rs3795575). B. The SNaPshot result of a patient carrying both the AGT haplotype C-T-A and haplotype t-c-g (SNP order: rs2148582, rs2478545 and rs943580). Lowercase denotes the minor allele at the locus and uppercase the major allele.
