Re: How can a genetic test tell you anything about an enzyme?

There are a couple of assumptions here !
Firstly, you have to have a medical condition caused by a deficiency in 
digesting food, which causes bloating and cramps.

Secondly, you have to be able to guess which enzyme is responsible- bear 
in mind that there may be quite a number of possible enzymes responsible.

thirdly, you have to be able to guess which is the likely mutation which 
causes the enzyme deficiency.

But YES- genetic tests can identify particular enzyme defects or 
deficiencies, and what exactly is wrong with the enzyme, in terms of 
primary structure.
