Genetic Disorder

It’s important to test Lee for genetic disorder with non-cancerous cells because in cancerous cells, countless mutations have already taken place. If we use a cell with mutations, it is hard to determine the problem in the first place or which parent/gene the disease is inherited from. The DNA sequence may also be altered which coded for Lee’s condition. Going forward with non-cancerous cell, if we test the relevant parent/gene then we can find out the identity of the genetic disorder.
