From the [MPD](http://phenome.jax.org/) website:
This resource is a collaborative standardized collection of measured data
on laboratory mouse strains and populations. Includes baseline phenotype
data sets as well as studies of drug, diet, disease and aging effect.
Also includes protocols, projects and publications, and SNP,
variation and gene expression studies.
Here, we pull the data and model the genotypes using GENO and
the genotype-to-phenotype associations using the OBAN schema.
MPD provide measurements for particular assays for several strains.
Each of these measurements is itself mapped to a MP or VT term
as a phenotype. Therefore, we can create a strain-to-phenotype association
based on those strains that lie outside of the "normal" range for the given
measurements. We can compute the average of the measurements
for all strains tested, and then threshold any extreme measurements being
beyond some threshold beyond the average.
Our default threshold here, is +/-2 standard deviations beyond the mean.
Because the measurements are made and recorded at the level of
a specific sex of each strain, we associate the MP/VT phenotype with
the sex-qualified genotype/strain.
