POLR2G encodes one of the subunits in the polymerase 2 RNA complex, which is responsible for transcribing protein coding genes, miRNAs, and some classes of non-coding RNAs [34] and maps to the 11q12.3 locus, within which variants associated with chronic obstructive pulmonary disease [35] and asthma [36] have been identified. Here, POLR2G is linked to asthma.
