Can someone explain how to relate CHROM and POS in VCF to the corresponding position in the referenced dbSNP?
For instance, in the following example:
#CHROM POS ID REF ALT 20 14370 rs6054257 G A
It looks as though the VCF is referring to a variant on Chr20 at position 14370, but the referenced dbSNP has HGVS NC_000020.10:g.66370G>A.
If the VCF record didn't include the dbSNP id, how would one convert this into an HGVS expression?
