According to this information 151 million Americans earned some sort of wages or compensation in 2011. The median wage in the US per person is $26,695. This tells us a lot since the median household income is at $50,500. Since the Census data looks at households, this data hones in on individual wage earners.
For several years, Dr. Wasmuth and his team had suspected that the gene, FGFR3, was responsible for a defect that causes Huntington's disease, a neurological disorder. But they found no link. They took another look after other researchers suggested that the same chromosome region might harbor the achondroplasia gene.
In most cases, this common type of short-limbed dwarfism is related to a genetic mutation in the fibroblast growth factor receptor 3 gene. There are two possible causes of achondroplasia. One possible cause is a genetic mutation in the fibroblast growth factor receptor 3 (FGFR3) gene located on chromosome 4.The other possible cause is that the condition can be inherited from a parent with achondroplasia.here are two possible causes of achondroplasia. One possible cause is a genetic mutation in the fibroblast growth factor receptor 3 (FGFR3) gene located on chromosome 4.
