Question 1#

You are seeing a 24-year-old man (A) referred by his GP as he is concerned about his risk of Fabry disease which runs in his family, as shown in the pedigree in Figure below

What is his risk of having the condition?

A) 0
B) 1 in 8
C) 1 in 4
D) 1 in 2
E) 1

Correct Answer is A


Fabry disease is an X-linked condition. Therefore it will not be passed on from a father to his son (as he will receive the Y chromosome from his father).
