Overview
Risk factors associated with the development of retinoblastoma are mutation in RB1 gene, a positive family history of retinoblastoma, living in areas with high incidence rate of the disease, HPV viral exposure and other environmental factors.
Risk Factors
Genetic mutations
- Retinoblastoma has been associated with the following genetic disorders:
- RB1 gene mutation
- Deletion of chromosome 13 long arm of (13q deletion syndrome)[1]
- Fragile x syndrome
Family history
- Approximately 10% of patients with retinoblastoma have a previously established family history of the disease.[2]
- The magnitude of risk among offspring of the proband depends upon the tumor presentation in the proband (ie, unilateral or bilateral) and the relationship of the individual to the patient with retinoblastoma.
- The table below provides the estimated risk of developing retinoblastoma in individuals with a positive family history of retinoblastoma.
| Relative of patient | Bilateral involvement (100%) | Unilateral involvement (15%) |
|---|---|---|
| Offspring (infant) | 50 | 7.5 |
| Parent | 5 | 0.8 |
| Sibling | 2.5 | 0.4 |
| Niece/nephew | 1.3 | 0.2 |
| Aunt/uncle | 0.1 | 0.007 |
| First cousin | 0.05 | 0.007 |
| The above table adopted from Ophthalmology journal [3] |
|---|
HPV virus exposure
- The presence of HPV sequences in retinoblastoma tumor tissue may play a role in the development of sporadic retinoblastoma.[4]
- There is evidence suggesting that the mutations of RB1 are more common during spermatogenesis than oogenesis.[5]
Environmental factors
- Epidemiological data indicated that retinoblastoma has higher incidence in some geographic areas. For more information click here.
- Other factors which has been associated with increased risk of retinoblastoma development include:[6]
- Mother’s use of insect or garden sprays during pregnancy
- Diagnostic x-ray with direct fetal exposure
- Father’s employment as a welder, machinist, or related metal worker
