总体来说，hg38相对于 hg19是一个巨大进步。by 员炊事

1. 改变了之前的一些测序错误，组装错误。直观的例子有 degenerate bases 少了很多。
2. 补上了hg19中的很多gap。 特别重要的是 centromere 的序列也不再是空白。hg19的时候，centromere 的部分直接就是gap， hg38后，开始有了 a-satellitle sequences。尽管只是“简单”的表现了 a-satellite repeats， 已经是一个巨大的提升。
3. sequence 改了之后，相应的 annotation 也改了很多。比较宏观的就是 hg38 的 exome 比hg19 的大了不少。如果我的记忆没出错的话，大了25% 左右。
