Shortcut to several different NCBI databases that have information about genetic variation: ClinVar - a crowdsourced database with clinical significance of variations, dbSNP - a database of single nucleotide and other small polymorphisms, and dbVar - a database of large-scale (>50 bases) variations. It includes link out from specific variations to published articles in PubMed related to that variation.

Database cataloging human genes and genetic disorders authored and edited by Dr. Victor A. McKusick and his colleagues at Johns Hopkins and elsewhere, and developed for the Web by NCBI. The database contains textual information and references.

SNP has information about small genetic changes, with links out to genome studies that have been done with populations around the world. SNP is searchable by gene as well as by identifiers such as rs numbers. SNP includes many organisms, not just humans, so be sure to narrow by organism if you're interested in human.
