We have read the paper “Oxidative stress and polymorphism in MTHFR SNPs (677 and 1298) in paternal sperm DNA is associated with an increased risk of retinoblastoma in their children: a case-control study.”[1] In fact, the effect of genetic polymorphism on retinoblastoma is interesting. Some polymorphisms are well studied for their association with retinoblastoma.[2] Previous reports have shown the relationship between MTHFR polymorphisms and retinoblastoma among patients.[3] This report is extraordinary since the investigation was not performed on a patient, but the genetic test was performed in paternal specimen. This is not a standard epidemiological investigation to assess the risk. There are several confounding factors such as material genetic component and environmental factors that can affect the final expression as retinoblastoma. To conclude on the association between MTHFR polymorphisms and retinoblastoma, additional study on samples from pediatric patients is required.
