Say you want to describe the impact of a mutation. There exists several dictionaries you could use, including
Sequence Ontology. These terms are what VEP uses
PAVE Consequences that the PAVE annotator supports (mostly a subset of SO terms but with a couple of additions to indicate when a non-obvious consequence can be found thanks to phasing)
mutationtypes makes it easy to check whether your vector of mutation types aligns to one of these dictionaries. It also simplifies translation from one dictionary to another.
Install from CRAN:
Alternatively, you can install the development version of mutationtypes like so:
library(mutationtypes)
# Check which mutation impact dictionary you're vector is closest too
mutation_types_identify(
c(
"INTRAGENIC",
"INTRAGENIC",
"intergenic_region",
"stop_lost",
"missense_variant",
"missense_variant"
)
)
