A 2 two year old male presents with a retinal tumor and ultimately

Retinoblastoma.


1. What is retinoblastoma, and what is the pattern of inheritance for

this type of cancer?



Retinoblastoma (RB) is a type of eye cancer that begins in the

retina, and is the most common intraocular malignancy in children.

During early development the eyes have cells called retinoblasts which

multiply to make new cells that fill the retina; during this process these

cells stop multiplying and become mature retinal cells (American Cancer

Society, 2021). In some cases, instead of these cells maturing, some

retinoblasts continue to grow out of control forming a cancer known as

Retinoblastoma (Alali et al., 2018).

There are two major genetic forms of Retinoblastoma, heritable

and non-heritable. Research has shown that one-third of all

vendarsol

, Retinoblastomas are hereditary (American Cancer Society, 2021). A

child may inherit one altered copy of the RB gene from a parent- making
