Genomic distribution of CNVR and their frequency in our samples. a Known and novel CNVR are distributed throughout the genome, with novel CNVR having lower frequencies compared to known CNVR. The centre of the circle has the least frequency of < 1% whereas the outermost bounds represent higher frequencies of up to 100%. Novel CNVR shown in red are lower frequency compared to known CNVR shown in black. A few known CNVRs show high frequencies. b Comparison of frequencies in the various populations. No major differences in CNVR frequencies were found between populations. All populations are represented in the plot with different colours. The centre of the plot has the least frequency of 0% whereas the outermost bounds represent higher CNVR frequencies. Frequencies are similar across populations. The frequencies of CNVRs with CNV frequencies < 20% are set to 0% to enhance visibility. Cyan shows the CNV frequency of those common to GAS and all populations, UBB are in black, DRC are in green, CIV are in dark blue and UGN are in red
