I have performed a GISTIC2.0 analysis in my samples, but after analyzing the results I found something that seemed a little off. In the results, there are some regions that are annotated to contain thousands of genes, e.g. 17q21.31 has 1018 genes according with the results. In the meanwhile, OMIM and http://atlasgeneticsoncology.org/ are showing far fewer genes for the same region. Has someone experienced the same?
Thank you. R
