1 in 1500 people.
is not my definition of rare. Sorry, I know you're an accountant...but as a social scientist that does not sound like a phenomenon or valid anomaly.
I used the word "rare" as the website (wrongdiagnosis . com) described it as such. The article I saw says this:
Fish-odor syndrome: Rare Disease
Office of Rare Diseases (ORD) of the National Institutes of Health (NIH)
Fish-odor syndrome is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Fish-odor syndrome, or a subtype of Fish-odor syndrome, affects less than 200,000 people in the US population.

Ophanet
Ophanet, a consortium of European partners, currently defines a condition rare when if affects 1 person per 2,000. They list
Fish-odor syndrome as a "rare disease".
So the ORD says it's rare, but the Orphanet definition puts the condition just outside rare. But wthether the condition is technically rare or not makes little difference to those who suffer from it
