[Genome] rsids mapping to multiple locations

[Amit Indap]

Hi UCSC

Sorry if I should be directing this to the  folks at
dbSNP, but I found a couple hundred rsids that map to
2 locations: a real chromosome and then to a
chrom*_random.

I was surprised to come across this. My guess these
records are passing their quality checks on snp
mapping at dbSNP. Some examples:

rs17139617 at chrX_random:1079290-1079790
rs17139617 at chrX:77161265-77161765

rs17732842 at chr3_random:293033-293533
rs17732842 at chr3:76384194-76384694
