Summary of the exome sequencing data and the identified single nucleotide variants.

The numbers of heterozygous variants are those that have a minimum of 5× coverage. The dbSNP percentage represents the portion of identified variants present in the Single Nucleotide Polymorphism Database.杂合变异（heterozygous variants）的计数指的是测序覆盖度至少为5倍的变异位点。dbSNP占比指的是已鉴定变异中，存在于单核苷酸多态性数据库（Single Nucleotide Polymorphism Database，简称dbSNP）中的变异位点所占的比例。
