How can you find out the coordinates of the PAR1 and PAR2 regions on chromosomes X and Y in the Ensembl human reference genome? As far as I can tell, these regions are masked with Ns on Ensembl (but not UCSC).
Now, the hard part (for me) is knowing the Ensembl gene IDs for PAR1 and PAR2, since PAR2 is apparently not an official gene human gene symbol, and the PAR1 in Entrez Gene doesn't have a match in Ensembl. But presumably you can find your Ensembl Gene ID more easily?
(Incidentally, NCBI Entrez Gene also will give genomic coordinates, and they use the same assembly as Ensembl...)
