The Phenotypic Feature element of the GA4GH Phenopacket Schema. This element contextualizes HPO annotations by allowing the severity, onset, resolution, and other characteristics (modifiers) of the phenotypic observation to be specified. In this example, two phenotypic observations are given: (i) severe, daily (quotidian) infantile spasms with infantile onset (between month two and twelve of life) and resolution at the age of 4 years, 2 months and (ii) exclusion of global developmental delay (that is, this feature was assessed and explicitly found not to be present).
