Overview

The goal of this observational study is undertake a detailed phenotypic and genotypic study of patients with ocular and secondary cancers due to mutations in the RB1 gene. Our research sequencing approach will allow advanced insight to for further detailed genotypic understanding of parent-of-origin for valuable insight into the genotype-phenotype relationship of this cancer syndrome.

• Able to give consent/parent or guardian able to give consent.

Exclusion Criteria:

• Patients unable or unwilling to undertake consent or clinical testing.
• Patients unwilling to donate a saliva or blood sample in order to establish the genetic cause of their condition.
