HPV gene integration frequency across different cervical cancer samples. Heatmap representation of HPV types detected across 17 cervical cancer samples. HPV16 in 13 samples, HPV18 in 2 samples, HPV71 in 6 samples, HPV82 in 5 samples, HPV31 in 2 samples, HPV45 in 5 samples, and HPV17, 56, 58, 15, 20 were detected in 1 sample, each. Total coverage of the exome sequencing is indicated in the last column ‘cov'. On the basis of read count, the abundance of HPV is graded in different samples: read counts 1–10 as light grey; read counts 10–50 as dark grey; and read counts >50 as black.
