Gene integrates information from a wide range of species. A record may include nomenclature, Reference Sequences (RefSeqs), maps, pathways, variations, phenotypes, and links to genome-, phenotype-, and locus-specific resources worldwide.

What is a gene?: MedlinePlus Genetics
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.

Gene - Wikipedia
A gene is a region of DNA that encodes function. A chromosome consists of a long strand of DNA containing many genes. A human chromosome can have up to 500 million base pairs of DNA with thousands of genes. In biology, the word gene (from Greek: γένος, génos; [1] meaning generation [2] or birth [1] or gender) can have several different meanings.

Gene
The gene is considered the basic unit of inheritance. Genes are passed from parents to offspring and contain the information needed to specify physical and biological traits. Most genes code for specific proteins, or segments of proteins, which have differing functions within the body. Humans have approximately 20,000 protein-coding genes.

Gene | Definition, Structure, Expression, & Facts | Britannica
gene, unit of hereditary information that occupies a fixed position (locus) on a chromosome. Genes achieve their effects by directing the synthesis of proteins. In eukaryotes (such as animals, plants, and fungi ), genes are contained within the cell nucleus.

Gene | Journal | ScienceDirect.com by Elsevier
Gene publishes papers that focus on the regulation, expression, function, and evolution of genes in all biological contexts, including all prokaryotic and eukaryotic organisms, as well as viruses. Gene strives to be a very diverse journal, and topics in all fields will be considered for publication (note that manuscripts on bioinformatics are only considered for review if they contain experiments).

Alzheimer's: Is it in your genes? - Mayo Clinic
The most common gene associated with late-onset Alzheimer's disease is a risk gene called apolipoprotein E (APOE). APOE e2 — the least common — reduces the risk of Alzheimer's. APOE e4 — a little more common — increases the risk of Alzheimer's and is associated with getting the disease at an earlier age. Approximately 15% to 25% of the ...
