Has anyone ever heard of a white doberman?

Apparently they have a similar gene to the recessive gene that causes white tigers and it has no problems that usually go along with white abnormals (deafness and blindness). Its not albino just a white recessive coloring. Ijust wondered if anyone else had heard of this or seen it. I was reading some veterinary gene studies on breeds with known origins (the original crosses) and came across it. Interesting reading and very useful if you want to know why certain inheirent diseases are breed specific (eg hypothyroidism,epilepsy and other diseases affecting the brain function). You come across the weirdest things and i have never heard of a white doberman.
