Centromeric breakpoint positions of the 11 atypical NF1 deletions with centromeric breakpoints located within SUZ12P . The exon-intron structure of SUZ12P is indicated as well as the numbering of the exons presented as vertical black lines. The extent of each of the 11 atypical NF1 deletions is shown by red bars. The telomeric breakpoints of these deletions differ from each other and are not indicated on this schema. The numbering of the centromeric breakpoint locations is given according to the human GRCh37/hg19 assembly. tel, telomeric direction.
