Point Mutation
... Hutchinson-Gilford progeria syndrome The disease is caused by a small point mutation on a single gene known as LMNA. Almost all cases are caused by the substitution of only one base pair out of the approximate 25 000 DNA base pairs that compose the LMNA gene. This gene codes for the protein lamin A ...

Epistasis
Epistasis is a phenomenon that consists of the effect of one gene being dependent on the presence of one or more 'modifier genes' (genetic background). Similarly, epistatic mutations have different effects in combination than individually. It was originally a concept from genetics but is now used in biochemistry, population genetics, computational biology and evolutionary biology. It arises due to interactions, either between genes, or within them leading to non-additive effects. Epistasis has a large influence on the shape of evolutionary landscapes which leads to profound consequences for evolution and evolvability of traits.
