Introduction # We have a list of genes, like:
EGFR MET TP53 And we want the genome positions plus 10 bases at each end for each exons, the results should like:
chr7 116672185 116672587 NM_000245_exon_0_10_chr7_116672196_f 0 + chr7 116699060 116700294 NM_000245_exon_1_10_chr7_116699071_f 0 + chr7 116731657 116731869 NM_000245_exon_2_10_chr7_116731668_f 0 + chr7 116739939 116740094 NM_000245_exon_3_10_chr7_116739950_f 0 + chr7 116740841 116741035 NM_000245_exon_4_10_chr7_116740852_f 0 + chr7 116755344 116755525 NM_000245_exon_5_10_chr7_116755355_f 0 + chr7 116757426 116757549 NM_000245_exon_6_10_chr7_116757437_f 0 + chr7 116757627 116757784 NM_000245_exon_7_10_chr7_116757638_f 0 + chr7 116758448 116758630 NM_000245_exon_8_10_chr7_116758459_f 0 + chr7 116759380 116759500 NM_000245_exon_9_10_chr7_116759391_f 0 + Method # UCSC Table Browser do this job perfectly, thanks.

Introduction # MPprimer: a program for reliable multiplex PCR primer design
BACKGROUND: Multiplex PCR, defined as the simultaneous amplification of multiple regions of a DNA template or multiple DNA templates using more than one primer set (comprising a forward primer and a reverse primer) in one tube, has been widely used in diagnostic applications of clinical and environmental microbiology studies. However, primer design for multiplex PCR is still a challenging problem and several factors need to be considered.
