Figure Lengend Snippet: Comparison of the number of genomes and populations between PGG .SNV and other frequently used data sets. a Geographical distributions of the population samples included in PGG .SNV. Each dot represents an ethnic group, and each bar denotes the number of genomes of the corresponding ancestry. b A comparison of the numbers of genomes included in the 1000 Genomes Project (1KGP), Exome Sequencing Project (ESP), The Genome Aggregation Database (gnomAD), and PGG .SNV. Each color represents an ancestry that was used in a . c A comparison of the numbers of populations or ethnic groups included in different databases. PGG .SNV includes 852 present-day populations and 125 ancient populations which is defined based on geography and time period

Figure Lengend Snippet: An example of the user-friendly method for visualization and accessing data. a Basic information for the selected SNV. Alt. Allele Frequency denotes the frequency of alternative alleles in the PGG .SNV database, with the alternative allele counts and total allele counts shown in brackets. The Modern Human Population Count represents the number of ethnic groups whose genomic data contain the selected variant in the PGG .SNV database. The Ancient Genome Count denotes the number of ancient genomic data sets that contain the selected variant in the PGG .SNV database. At the bottom of a , there are nine annotation cards for a selected variant. Users can switch them to visualize the corresponding annotation. b Allele frequencies of the variant across worldwide populations. The figure is interactive on the web, with an allele frequency pie chart of each population in a worldwide map where geographic locations represent the position of slices for corresponding populations. It has embedded mouse-scrolling events allowing the user to zoom in and out the resolution, a mouse-hovering event on a slice to get detailed information, and a figure- and table-switching event. c Custom pop-up windows for selecting populations, ancestries, and data sets. Note that the choices between population, ancestry, and data set buttons are related but not independent. d Allele frequencies of a variant in different data sets. e WeChat Quick Response (QR) code for access to the information including that in the PGG .SNV database. Users can scan the code and follow the PGGbase official account to access data via a smart phone

Figure Lengend Snippet: Prevalence and differentiation of Mendelian disease variants across populations. a Allele frequency spectrum of Mendelian-inherited disease variants. Mutations are grouped into five categories by their severity (see “ ”). b Rareness and population and ancestry differentiation of Mendelian-inherited disease variants. c An example of a pathogenic variant (rs78838117) that shows high DAF in some Southeast populations such as Bateq people (DAF = 0.33), Jakun people (DAF = 0.15), and Mendriq people (DAF = 0.125) in Malaysia. The corresponding PGG .SNV link is https://www.pggsnv.org/searchinfo.html?key=11-2930440-G-A . d An example of a pathogenic variant (rs41469351) that shows high DAF in some West Africa populations such as the Gambian people (DAF = 0.36). The corresponding PGG .SNV link is https://www.pggsnv.org/searchinfo.html?key=3-46412262-C-T . e An example of a variant (rs12917189) that shows large differentiation between Africans and non-Africans.
