I am trying to retrieve full gene lists for a given GO id (like "GO:0060973"), limiting to human genes. The R code I am using is shown below. When run, just two genes are returned, but the AmiGO2 page for that pathway https://amigo.geneontology.org/amigo/term/GO:0060973 returns 20 or so genes.

I think this is because my query is only returning genes with a "GO class (direct)" exactly matching the queried pathway ("cell migration involved in heart development"), but I would like to also include the genes from sub-pathways shown on the AmiGO2 page (like "cell migration involved in coronary vasculogenesis").

I know I must be able to specify this in the filters somehow, but I have been searching for quite a while and just can't figure it out.

library("biomaRt")

ensembl = useMart("ensembl",dataset="hsapiens_gene_ensembl")

gene.data <- getBM(attributes=c('hgnc_symbol', 
'ensembl_transcript_id', 'go_id'), filters = 'go', values = 
'GO:0060973',mart=ensembl)

unique(gene.data$hgnc_symbol)

[1] "BVES"  "NDRG4"

Using biomaRt:

> mart <- useEnsembl("ensembl","hsapiens_gene_ensembl")
> getBM(c("ensembl_gene_id","hgnc_symbol", "go_id"), "go_parent_term", "GO:0060973", mart)
