Context:
We observed a significant association between neuroblastoma and the common minor alleles of three consecutive single-nucleotide polymorphisms (SNPs) at chromosome band 6p22 and containing the predicted genes FLJ22536 and FLJ44180 (P=1.71x10–9 to 7.01x10–10; allelic odds ratio, 1.39 to 1.40).
===========================
It seems that the author refers to "chromosome band 6p22 contains the predicted genes..."
But why the author used "and" before "containing"?
