Distribution of single-copy intervals (▪) along genomic sequences containing (A) HIRA, (B)MAGEL2, and (C) CDC2L1 loci. Genomic sequence coordinates are derived from the GenBank accession numbers for each locus (see Methods and Results). Each point corresponds to the length of each single-copy interval on the y-axis at the genomic coordinate. The first position in panel A corresponds to position 798334 of GenBank accession no. NT_001039. TheHIRA gene is transcribed from the antisense strand of NT_001039 and corresponds to positions 900363–799527. The intervals containing probe sequences used in this study are boxed and labeled with the relevant features of genes from these regions. IVS indicates intron; 3′UTR, 3′ untranslated region; and CDS, coding sequence.
