New here. No diagnosis. Question about testing?

Hi. I know that you all, unfortunately, have a lot of experience and knowledge about CF so I hope you don't mind me crashing your party. :o My son just turned 18 yrs old. A while ago, he brought this white bubbly rash on his palms to my attention. You know where I'm going with this. I did some googling and brought him to the dermatologist. He immediately confirmed my amateur diagnosis of Aquagenic Wrinkling of the Palms. My son said that they really start to hurt after his shower and the skin just falls off. The doctor prescribed some Aluminum Chloride solution to apply to his palms but my son never uses it. He has high functioning Autism which throws another wrench into all of this! The dermatologist didn't seem alarmed but said he would refer us for a genetic consultation at Yale if I wanted to go that route. I definitely want to get this checked out. Naturally, I'm a bit worried. I don't think my son was tested at birth and neither my husband or I have ever been tested. No family history that we are aware of -- but my husband has never met his father or anyone on the paternal side of his family. Do you know what the odds are that this is linked to CF? Is it likely to be just a fluke? Am I doing the right thing by pursuing this? Also, please inform me as to what sort of testing I should be sure to have done. Best to all of you -- and thanks! Stacey
