Hi Animesh, The duplicate entries you are seeing are from refSeq genes that aligned to more than one location. There are many such entries. Note this part of the RefSeq track description: "RefSeq RNAs were aligned against the human genome using blat; those with an alignment of less than 15% were discarded. When a single RNA aligned in multiple places, the alignment having the highest base identity was identified. Only alignments having a base identity level within 0.1% of the best and at least 96% base identity with the genomic sequence were kept."
