Erg (landform) and western Asia, and Central Australia. In South America, ergs are limited by the Andes Mountains, but they do contain extremely large dunes in coastal Peru and northwestern Argentina. They are also found in several parts of the northeast coast of Brazil. The only active erg in North America is in the Gran Desierto de Altar () that extends from the Sonoran Desert in the northwestern Mexican state of Sonora to the Yuma Desert of Arizona and the Algodones Dunes of southeastern California. An erg that has been fixed by vegetation forms the Nebraska Sandhills (). Sand seas and dune
ERG (gene) Sarcoma cases have an EWS1-ERG fusion. In acute myeloid leukemia, the t(16;21) translocation in myeloid leukemia fuses TLS/FUS to ERG which disrupts the natural TLS/FUS RNA binding domain, and instead inserting the ERG DNA binding domain. "ERG" is located on chromosome 21. The ERG protein is expressed at a similar level throughout the body. "ERG" has been shown to interact with: ERG (gene) ERG (ETS-related gene) is an oncogene. ERG is a member of the ETS (erythroblast transformation-specific) family of transcription factors. The "ERG" gene encodes for a protein, also called ERG, that functions as a transcriptional regulator. Genes in
