Question

[BioInfo1010]

can i download SNPs data(rsID,chromosomal position, function, variation class, contig,contig position,Allele etc..) of a gene from dbSNP using eUtils?

eg. i want to download SNPs data(rsID,chromosomal position, function, variation class, contig,contig position,Allele etc..) of DMD gene using eUtils.

Get the ID of your gene: e.g: http://www.ncbi.nlm.nih.gov/gene/4853

retrieves the SNP id with NCBI ELink: http://eutils.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=gene&db=snp&id=4853

http://www.ncbi.nlm.nih.gov/entrez/query/DTD/eLink_101123.dtd">
<eLinkResult>

    <LinkSet>
        <DbFrom>gene</DbFrom>
        <IdList>
            <Id>4853</Id>
        </IdList>
        <LinkSetDb>
            <DbTo>snp</DbTo>

             (....)

fetch the SNP data with ncbi efetch:
