AI Article Synopsis
- The Rb2/p130 gene, linked to several cancers, was investigated for mutations in nasopharyngeal carcinoma (NPC) samples from Malaysia.
- Only one out of 53 samples showed a mutation, specifically a serine to glycine change at codon 995 (S995G).
- The findings suggest that mutations in the Rb2/p130 gene are rare in NPC and may not significantly contribute to the development of the disease.
Article 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.
