  • Title: Lack of Rb2/p130 genetic alteration in Malaysian nasopharyngeal carcinoma.
    Author: Hoe SL, Lee ES, Khoo AS, Peh SC.
    Journal: Malays J Pathol; 2009 Jun; 31(1):53-6. PubMed ID: 19694314.
    Abstract:
    The retinoblastoma-related gene Rb2/p130 has been reported to be mutated in several malignancies such as lung cancer and Burkitt's lymphoma. Nasopharyngeal carcinoma (NPC) is a common cancer in Malaysia especially amongst the ethnic Chinese. We screened for Rb2/p130 gene (exons 19 to 21) mutations in 53 archival NPC samples via PCR-SSCP-direct sequencing approach. Only one sample had a base change which involved a serine to glycine substitution at codon 995 (S995G). We conclude that Rb2/p130 genetic alterations are infrequent in NPC and may not be essential for the pathogenesis of the disease.
