I'm attempting to map some rsids to chromosome and position on hg19 via biomart. I've run into several cases where a single SNP will return multiple entries for chromosome and position.
refsnp_id chr_name chrom_start chrom_end rs2950012 17 43667365 43667365 rs2950012 HG1146_PATCH 43777997 43777997 rs2950012 HSCHR17_1 44585673 44585673
As per a prior post, I noticed that the patches can be assigned to a particular chromosome. I'm curious which is the correct out of the three and should be retained in a situation like this - the patch, or the one mapped to chr 17?
