This article mainly introduces how to convert ENSEMBL ID into Gene ID or Symbol in R language, which has a certain reference value, and interested friends can refer to it. I hope you can learn a lot after reading this article.

AnnotationDbi and the annotation file corresponding to the binding species, convert ENSEMBL ID to Gene ID (ENTREZID)

How to use ENSEMBL ID to get Gene ID (ENTREZID) in R, or convert it to Gene Symbol, take people as an example:

Pre-install AnnotationDbi and org.Hs.eg.db

Load org.Hs.eg.db

> library (org.Hs.eg.db)

Get all the ENSEMBL ID and view the first five ID

> k=keys (org.Hs.eg.db,keytype = "ENSEMBL") > head (KM5) [1] "ENSG00000121410", "ENSG00000175899", "ENSG00000256069", "ENSG00000171428" and "ENSG00000156006"

Based on the extracted ENSEMBL ID, extract all the corresponding Gene ID (ENTREZID) (and Symbol), and take a look at the extracted content.

> list=select (org.Hs.eg.db,keys=k,columns = c ("ENTREZID", "SYMBOL"), keytype= "ENSEMBL") 'select ()' returned 1:many mapping between keys and columns > dim (list) [1] 29140 3 > head (list,5) ENSEMBL ENTREZID SYMBOL1 ENSG00000121410 1 A1BG2 ENSG00000175899 2 A2M3 ENSG00000256069 3 A2MP14 ENSG00000171428 9 NAT15 ENSG00000156006 10 NAT2

Pre-prepared ENSEMBL ID, how to find their corresponding Gene ID (ENTREZID) and Symbol, such as in ID, to get the corresponding relationship: ID_list
