Fig. 2From: “Monoallelic germline methylation and sequence variant in the promoter of the RB1 gene: a possible constitutive epimutation in hereditary retinoblastoma”Shows a representative electropherogram of “C” clone with the sequence variant and “W” clone without the sequence variant in PBL of the index case (the sequence variant between ATF- and E2F-binding sites changes TT bases of the wild sequence to GG in “C” clones). The CpGs 16 to 19 are includedBack to article page
