Abstract

Taiwan Biobank (TWB) project has built a nationwide database to facilitate the basic and clinical collaboration within the island and internationally, which is one of the valuable public datasets of the East Asian population. This study provided comprehensive genomic medicine findings from 1,496 WGS data from TWB. 

We reanalyzed 1,496 Illumina-based whole genome sequences (WGS) of Taiwanese participants with at least 30X depth of coverage

サンプル数、分析深度とも充分である

Background

In Asia, a genetic reference panel based on 3,552 individuals of the Japanese (JPN) population was published in 2019 [2] [3].

Another study based on 4,810 Singaporeans (SGN) was published in 2019 by the SG10K project [4].

Methods

All 1,496 Taiwanese WGS data were collected and de-identified at Taiwan Biobank (TWB). WGS were conducted separately in three batches (n = 496, 497, and 503, respectively) with high-depth mapped reads. The samples were sequenced by Illumina HiSeq 2500, 4000, and Novaseq system. Sequencing of DNA extracted from each blood sample generated about 90 GB of data with an average coverage of 30x

Results

The status of carrier variants in Taiwan, Singapore, and Japan To address the uniqueness of Taiwanese, we compared the MAF of 1,136 carrier variants in two different East Asian populations, e.g., Japanese and Singaporean. There were 279 common carrier variants between Japanese and Taiwanese and 611 common carrier variants between Singaporean and Taiwanese (Fig. 3).

Annotated functional effect and occurrence of all passed variants. The spectrum between the alternative allele counts and the number of variants in different categories. The variants were categorized based on the ANNOVAR ExonicFunc.RefGene annotation. LOF: loss of function, including frameshift_deletion, frameshift_insertion, stopgain, and stoploss. non-frameshift: including non-frameshift_deletion and non-frameshift_insertion. nonsynonymous: non-synonymous_SNV. synonymous: synonymous_SNV.

やはり、ゲノム全体で非同義変異比率は、MAFで50%を少し超える程度に過ぎない。
