The Adnab-9 level standardized for protein was 2 times higher in Twin #2 than that of the FAP patient and 2.7 times higher than that of the control when expressed in terms of percent of positive control in Adnab-9 binding (a membrane-enriched tissue extract of a colonic adenoma) and depicted in Figure 1A. The gene discussed is FAP; the disease is colon adenoma.
