Chang Tai-jay, associate principal investigator at the Genome Research Laboratory of the Department of Medical Research and Education, Veterans General Hospital Taipei, points out that ARCAP cannot be used to predict whether a person will acquire a congenital gene that causes liver cancer, but it does facilitate the early detection of postnatal mutations in liver cancer genes.
但發現此一基因的台北榮總教學研究部副研究員張泰階則指出，ARCAP 並不是一個預測某個人會不會得肝癌的先天基因，而是一個可供醫界及早發現肝癌的後天變異基因。
