What tools can I use to look up my alleles, genotypes, or phenotypes from my sequenced DNA (WGS)?
If this is your own DNA and you are trying to analyse yourself you should talk to a genetic counselor. I personally think it's cool, but I deeply understand the potential consequences.
What you want is a variant annotation tool. There are many, but I normally write my own. Which is simply a case of pulling down a database and using pandas to match variants with annotation.
There are many databases. The biggest popular database is gnomad and the biggest disease database is clinvar. Others include omim, snpdb and 1k genomes. I'm not sure about blood sorry but I'm sure you can find one.
