Mutational analysis of the RB1 gene and the inheritance patterns of retinoblastoma in Jordan.

Retinoblastoma (RB) is a childhood cancer developing in the retina due to RB1 pathologic variant. Herein we are evaluating the oncogenic mutations in the RB1 gene and the inheritance patterns of RB in the Jordanian patients. In this prospective study, the peripheral blood of 50 retinoblastoma patients was collected, genomic DNA was extracted, mutations were identified using Quantitative multiplex PCR (QM-PCR), Allele-specific PCR, Next Generation Sequencing analysis, and Sanger sequencing.
