A very broad biological term describing the effect of a gene or alteration of a gene on a phenotype. Usage is created by the context, which can be complex. Some genes have a multiple range of effects across a range of traits and characteristics of organisms. If the subject gene alters, it will have a multiple range of effects on the organism, hence the descriptor operates as defining a type of condition.

|Phenylketonuria: Multiple effects on the subject including reactions to phenylalanine, hair loss, in some cases skin pigmentation.|
Arachnodactyly: Causes long fingers and other physical effects.
