It is unknown whether this region has a tumor suppressive function, but more than 12% of primary prostate tumors show copy number loss of the 3p13-14 region from FOXP1 to SHQ1 (termed FOXP1-SHQ1 deletion) and 15% show copy number loss of the individual FOXP1 or SHQ1 genes that bound the deletion. This evidence concerns the gene FOXP1 and neoplasm.
