Are the Siberian and Russian Blue cat breeds naturally hypoallergenic?

Scientists have named one of the proteins in the feline saliva, FEL D-1. When the cat cleans itself, the protein then dries on the fur leaving dander. The dander particles are small and air filters cannot remove them from the air. The Siberian is practically void of the FEL D1 protein, therefore little or no dander. However if the allergic party suffers from the IgE late trigger' antibody reaction, their chances of compatibility of owning a Siberian are lowered.

"It is important to dispel two myths about Russian Blue cats" (source: http://www.mishablu.com/AboutRussianBlue… "1) Russian Blue cats are NOT hypoallergenic. They are just like any short haired cat which means if a person is allergic to cats, they will also be allergic to Russian Blues." (http://www.mishablu.com/AboutRussianBlue… "2) Russian Blues DO shed just like any other short haired feline. Every house cat must shed its fur in order to keep its coat in good condition.+ (http://www.russianblue.info/russian_blue… "Every cat sheds, however you'll find that the Russian Blue sheds very little, provided they are on a good balanced diet. You may see more shedding in spring and fall, while the cat changes seasonal coats."
