It is like asking: is blindness, paralysis, cancer, stupidity, ignorance, cruelty, and all the other psychological, physiological, and sociological maladies that afflict human kind, a test from god.
These type of test will presuppose a cruel, capricious, and not Omnipotent god. What happen if you fail the test. What scenario could cause more torment than GID.
Why would god make a test that cause afflicted people to kill themselves? There is no human affliction with a higher rate of suicide !
IMO GID is but due to a biological mishap, and like many human affiction the product of random and/or chaotic effects, nothing less or more. God has nothing to do with it.
