However, when grade 2 carcinomas were compared with grade 3 carcinomas, grade 2 carcinomas showed higher rates of low expression of SMP30 (76% (19 of 25) vs. 64% (16 of 25)) and lower rates of moderate expression of SMP30 (24% (six of 25) vs. 28% (seven of 25)) (Figure 6C). The gene discussed is RGN; the disease is carcinoma.
