In the present study, additional cases of IP, IP + SCC, SCC, and CRS were recruited and HPV status (presence, viral load, and physical status) and cell cycle proteins related to HPV infection— retinoblastoma (pRb), p53, and p16INK4a gene products—were investigated to reinforce our assumptions from the previous study. The gene discussed is RB1; the disease is congenital rubella syndrome.
