title: Find transcription start sites with biomaRt
body: <p>I am using <code>biomaRt</code> in R to query ensembl's <code>hsapiens</code> database of human genes. I am using the function <code>getBM</code> to get all genes' name, start position and stop position, but I cannot find the right attribute for retrieving the TSS (transcription start site). Is it maybe because it is considered the same as the <code>seqType= c("3utr", "5utr")</code>?</p>
