The gnomAD browser provides information on variants of genes (in this link, for the SAMD11 gene.) The report on a particular variant, like this one, includes the information in the header that says (for example): "This variant falls on 5 transcripts in 2 genes."
What does this mean? In particular, how can a variant occur on more than one gene? Isn't such a variant a variant of a particular gene -- SAMD11 in this case?
