UCSC Genome Browser on Human Mar. 2006 (NCBI36/hg18) Assembly

注解： NCBI36的数据和Ensembl的数据ENSG00000206338完全吻合，但是和GRCh37的数据有较大差别，所以记住比对数据均来自NCBI36或者Ensembl ENSG00000206338 (1000 genomes)，intron 2的长度是282bp.

但是，1000genome 显示有6个不同的CYP21A2 protein链接，相对应有3个ENSG （ENSG00000206338, ENSG00000198457 and ENSG00000168482），SEQUENCHER显示它们之间有9个不匹配的位置，但是没有gap差异，也就是长度上没有不同。
