Allele-specific methylation at the FAM50B locus. (A) Clones obtained from bisulfite-treated conceptus liver DNA are either predominantly methylated or unmethylated from the 18th CpG site to the 66th CpG site. (B) Clones obtained from bisulfite-treated conceptus liver DNA, representing one of three individuals heterozygous for SNP rs2239713 (arrow), while their matched maternal deciduae are homozygous G/G for the SNP sites. The allele-specific distribution of methylation with respect to the G/A polymorphism demonstrates that the maternally-derived allele is methylated while the paternally derived allele is unmethylated. (C) Clones obtained from bisulfite-treated mature sperm DNA are completely unmethylated. CpG sites are represented by circles. Unfilled circle, unmethylated CpG site; filled circle, methylated CpG site.
