In the comparison of the diagnostic usefulness between BSND and ATP6V1G3, a subset of clear cell RCC and a subset of papillary RCC cases showed weak ATP6V1G3 expression in the tumor cells; therefore, BSND immunohistochemistry may be more reliable than ATP6V1G3 immunohistochemistry from the perspective of diagnostic utility. This evidence concerns the gene ATP6V1G3 and neoplasm.
