When you want to search for scientific articles, there are various specialised search engines you can use. For articles related to biology and medicine, the best one is considered to be NCBI's PubMed at www.pubmed.gov. To find scientific articles on all fields of science, you can also try Google Scholar: scholar.google.com. To search OMIM, go to the NCBI and select OMIM from the pulldown menu on the top left, enter the gene or protein name you want to search in the text field and hit the Go button. In the results list you can click on the identifiers to go to the corresponding OMIM page. Since you are interested in the effect of SNPs in this gene, OMIM dbSNP link is useful.
