Figure 5From: Identifying diagnostic DNA methylation profiles for facioscapulohumeral muscular dystrophy in blood and saliva using bisulfite sequencingPCR haplotyping. (A) BS PCR products for subjects 75204 and 75205 using the 4qA DUX4 gene body primer set (left) or a primer set that non-specifically amplifies both 4qA and 10qA. BL: blood (PBMCs) and SA: saliva. (B) Genomic PCR amplification for either the 4qA or 4qB subtelomeres [15], as indicated. Although the 4qA D4Z4 gene body BS PCR did not produce a product for subject 75205 (No), standard PCR for 4qA alleles did produce a PCR product. These products were sequenced and confirmed as being 4C166H. These data together indicate that subject 75205 has a 4qB/C166H genotype. Additional predicted genotypes are indicated.Back to article page
