From the project's start in 1988 until now, about 3,000 complete human genes have been found.

The same genes are found in other animals as well.

However, the gene and protein have not yet been found.

Longer term, scientists around the world are trying to find genes involved in the disease.

No specific gene has been found to be associated with the disorder.

So far at least 25 different genes have been found to be involved in the development of mouse teeth.

C21orf59 is a gene found on the 21st chromosome at 21q22.1.

That was in the early 1970's, when scientists were just beginning to learn to find and manipulate genes.

Many different abnormal genes have been found that can cause Pick's disease.

The Mexican government has not disclosed exactly what genes were found.
