Dear All.

I am a user of 1000 genomes database, I have downloaded vcf file from UCSC (http://hgdownload.cse.ucsc.edu/gbdb/hg19/1000Genomes/phase3/).

In Chromosome X(ALL.chrX.phase3_shapeit2_mvncall_integrated_v1b.20130502.genotypes.vcf.gz), I found some repeat position, just like follows:

265 X       60072   .       G       C       100     PASS
266 X       60072   .       G       C,T     100     PASS

290 X       60233   .       C       G       100     PASS
291 X       60233   .       C       G,T     100     PASS

I don't know what happened on these sites? If you have some suggestions, please tell me.

Thanks.
