mapping snps to fucntional class and genes
Hi,
I have mapped a set of SNPs (rs#) using biomart within R to consequence types, but there are cases where each SNP is mapped to multiple functional class types with identical chromosome and position. How do I resolve the ambiguity and select the correct functional class.
Thanks

Usually this is the case where a single SNP has multiple effects. For example a SNP could have a non-synonymous effect on one gene while being downstream of another. One thing you can do in such a scenario is shortlist the most damaging effect. If you use a different tool base then snpEFF+GATK VariantAnnotator can do this for you.
