Size and distribution of 14 HVR-alleles identified by sequencing and gel electrophoresis.

The •/× indicate that the size of the allele was determined by both agarose gel images and sequencing, whereas filled circles (•) denote that the allele size was estimated from agarose gel images.The two most common alleles (HVR1098 and HVR1700) are highlighted in bold and underlined text.The sample indicated by a single asterisk (*) are from breast cancer patients. BL, PT and UM indicate peripheral blood DNA, primary breast tumor and healthy morphologically normal breast tissue from a patient affected with breast cancer, respectively.The samples indicated by two asterisks (**) are monozygotic twin pairs.
