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.
The odds vary with diagnosis, but a person with achondroplasia has one dwarfism gene and one average-size gene. If both parents have achondroplasia, there is a 25 percent chance their child will inherit the non-dwarfism gene from each parent and thus be average-size. There's a 50 percent chance the child will inherit one dwarfism gene and one non-dwarfism gene and thus have achondroplasia, just like her or his parents.
