3.1 × 10−2) of enrichment of DNase hypersensitive sites in undifferentiated embryonic stem cells. The UTP20 gene on chromosome 12 is a component of the U3 small nucleolar RNA protein complex and is involved in 18S rRNA processing (Wang et al., 2007). One of the most strongly associated SNPs, rs2270861 (p = 6.79 × 10−8) in UTP20 is predicted to be a trans eQTL for the olfactory receptor family 5, subfamily T, member 2 (OR5T2) gene on chromosome 11, as observed in data of Dixon et al (2007).
