FHIT expression is consistent across most tissues, but was highest in CD4 T-cells; modestly increased expression is observed in a variety of other tissues/cells, including CD34 cells, the hypothalamus, and whole brain; expression is also observed in every brain region for which data is available. OXTR is highly expressed in lymphoblasts, although datamining resources (http://www.ncbi.nlm.nih.gov/unigene) also indicate increased expression in the brain, skin, and breast. As with FHIT, OXTR is modestly expressed in all brain regions reported in BioGPS. FAF1 expression is increased in testis tissues, as well as in various blood cells and cancerous cells. WDR7 expression is highest across multiple brain regions, but especially in the amygdala, prefrontal cortex, and hypothalamus. SPATA13 exhibits increased expression in various blood cells, though expression is also detected across brain tissues. OPA3 is expressed consistently across brain tissues, though its highest detected expression levels are in cancer cells. No expression information is available for EFHA2.
