Penetrance as a percentage or fraction

[mbrush]

penetranceQualifier is currently a MappableConcept. However, penetrance is also sometimes reported as a numeric percentage of individuals with the genotype who exhibit the phenotype. How would we represent a numeric percentage in the MappableConcept?

From mbrush:

Good point Mrinal. We could add number as an allowable data type for this qualifier. Or introduce a separate penetranceQuantifier attribute for more quantitative descriptions of penetrance. We can decide which makes the most sense when there is a concrete use case requiring this (let us know if you have one now!)

This will be triaged to a future version unless implementations bring a concrete use case that require support in the 1.0 release.

I'm ok with that. We currently represent penetrance as a number in our system, but it has been populated pretty infrequently (at least in the past). If it becomes more common, we can revisit this.

Want to keep this issue open, as it will need to be addressed in the future. But won't tag it to do for the 1.0 milestone.
