I need to download dpsnp of rat. I used dbsnp ftp site and found under organisms there are two data sets for rat rat_10116 and rat_10118 Are they different strains??
Moreover, dpsnp vcf files for rat has SAO which is defined as follows:
##INFO=<ID=SAO,Number=1,Type=Integer,Description="Variant Allele Origin: 0 - unspecified, 1 - Germline, 2 - Somatic, 3 - Both">
For snps with SAO=0 . Is there any possibility that they are somatic variants??
Any help is appreciated.
