Question

[jananiinfo14]

I have above 15000 genes.each gene contain lot of variants and structure variants.In dpSNP database contains acertainment sample size for all variants.I need all sample size for all variants.it take lot of time for collecting manually.so please suggest me,if any other method or any programming script(particularly perl script)is there to collect these information. PLS CHECK for Acertainment sample size of one of the ncbi assay id of one variant https://www.ncbi.nlm.nih.gov/projects/SNP/snp_ss.cgi?subsnp_id=712886806
