Strong cis-acting expression quantitative trait loci for the genes encoding SNHG5 and PEX6.

ABSTRACT: Expression of quantitative trait loci (eQTLs) for the genes located in human chromosome 6 were examined. Data on RNA expression in lymphoblastoid cells of 373 unrelated Europeans were used to identify eQTLs.Genome-wide analysis resulted in 24,447 nucleotide variants associated with gene expression (P < 2.16 × 10). We found 36variants with P < 10, which were all associated with expression levels of the genes encoding small nucleolar RNA host gene 5 (SNHG5) and peroxisomal biogenesis factor 6 (PEX6). Enhancer eQTLs downstream of theSNHG5 gene might be candidate genetic factors for susceptibility to cancer. This is because nucleotide substitutions (eg, G→T at rs6922) of the enhancer eQTLs may cause low expression of SNHG5 gene, and low expression of snoRNA U50, a product generated from intron
