Question

Lay out the genetics of Nicholas’s case, including where the mutation
occurred, what exact nucleotide defect was present, why this was a
serious type of defect, and why he was so affected by the mutation
but his mother was not.

Expert Solution
Step 1

Nicholas was a 2 year-old boy with an extreme case of inflammatory bowel disease and susceptibility to infections. After continued deterioration of his lower intestine, his colon had to be removed. He was suspected to be suffering from a genetic disease, and his DNA was analyzed to find out which mutation was causing his condition.
