Hello,

I try to follow biomaRt tutorial to Retrieve all HUGO gene symbols of genes that are located on chromosomes 17,20 or Y, and are associated with specific GO terms.

getBM(attributes = c('hgnc_symbol', 'chromosome_name'),
      filters = c('go', 'chromosome_name'),
      values = list(go, chrom),
      mart = useMart("ensembl", dataset = "hsapiens_gene_ensembl"))

I only got three results:

hgnc_symbol chromosome_name
1        E2F1              20
2     RPS6KB1              17
3        CDK3              17

But if I want to add go_id into the attributes, then I got many results:

getBM(attributes = c('go_id', 'hgnc_symbol', 'chromosome_name'),
      filters = c('go', 'chromosome_name'),
      values = list(go, chrom),
      mart = useMart("ensembl", dataset = "hsapiens_gene_ensembl"))

Results:

Is it due to that one gene is related to several GO ID?

Besides, there is no Y chromosome result. Not sure if it is indeed no gene in Y or I missed something.

Thank you!

First, yes, one gene could be related to several GO ID, and the result is based on the annotation package you use.

Second, could you provide more context about the variable go and chrom? Maybe you want to make sure that chrom contains 17, 20, and Y. I believe this annotation has information about the genes that have GO terms associated and are on Y chromosome, and it is named as 'Y'. I double-checked this through the code below:

getBM(attributes = c('chromosome_name'),
      filters = c('with_go'),
      values = T,
      mart = useMart("ensembl", dataset = "hsapiens_gene_ensembl"))

It outputs a long list of the names of chromosomes including Y.
