Convert Cds-Based Coordinate To Genomic Coordinates

I was given a list of loci of interest for a particular gene, which contain mutations: unfortunately, all the information are using local base coordinates, while I'm in need to retranslate them to genomic coordinates to perform some additional work in preparation for validation. I've seen a few example of genomic -> local coordinate transformation, but not the opposite.

Bear in mind that I have access to the whole annotation of the genome (Homo sapiens), so using additional files and/or resources wouldn't be a problem.

Is there a way to convert from local coordinates to genomic coordinates? Python or R solutions would be preferred.

It's Homo sapiens.

Is this the problem where you have variants reported on transcript level like g.195insCTGATA in RB1 gene? Having the same problem here... I am looking forward to Pierre's solution

More like genomic sequence (all the coordinates are mapped to the canonical variant of the gene), but yes, something like that.

Ensembl REST API. Scroll down to Mapping to see tools to get genomic coordinates from cDNA, CDS and protein coordinates. Since it's a REST API, you can use it in your favourite language.
