With President Bush cutting down federal budget for medical research, NIH is lucky to receive infusion of funds from private firms.

Pfizer Inc. and Affymetrix Inc. are giving more than $20 million dollars to NIH to fund a project called the Genetic Association Information Network. The project aims to study the human genome map and identify tiny differences -- known as SNPs, or single-nucleotide polymorphisms -- that are determine actual disease risks.

Pfizer, the world's largest drug maker, is donating $5 million to help start that project, plus $15 million in laboratory studies to do that analysis for five common Diseases. Biotechnology company Affymetrix Inc., a leading maker of gene-analysis equipment, is donating the resources for similar DNA analysis for two additional diseases.
