Abstract

Hidden among the myriad nucleotide variants that constitute each species' gene pool are a few variants that contribute to phenotypic variation. Many of these differences that make a difference are non‐coding cis‐regulatory variants, which, unlike coding variants, can only be identified through laborious experimental analysis. Recently, Cowles et al.1 described a screening method that does an end‐run around this problem by searching for genes whose cis regulation varies without having to find the polymorphic nucleotides that influence transcription. While we will continue to require a diverse arsenal of experimental methods, this versatile method will speed the identification of functional genetic variation.
