SNORD33 and lung carcinoma: This data suggests that SNORD66, SNORD76 may act like oncogenes in lung cancer, as they are located in two of the most amplified chromosomal segments in solid neoplasm (19q13.3 and 1q25.1), while SNORD33 is encoded by chromosome 19q13.3 which contains different oncogenes involved in lung cancer and other solid tumors [269-272].
