If you know the description for the gene that you are trying to find, enter a keyword(s) from that description in the space(s) provided and click "Search&. If you use two terms, be sure to verify which search option button is active. The "AND" option should be selected if the item should contain both search terms. The OR option should be checked if the item should contain either term or both terms. It should be noted that this is the least efficient approach and frequently misses finding your gene of interest because what you think should be in the description is not. Worse, it may return numerous entries that are irrelevant but contain the keyword(s) entered. As such, this search method should be used only if you are unable to search by any other method.
