Gene expression is subjected to various random processes (referred to as ‘noise’) that contribute to variability in molecular phenotypes. As Eling, Morgan and Marioni describe, there are various challenges to studying this variability, such as disentangling its multilayered sources, distinguishing it from deterministic influences on cellular variability, modelling it with appropriate statistical methods and understanding its practical consequences.
