Description. While dwarfism is sometimes used to describe achondroplasia, a condition characterized by short stature and disproportionately short arms and legs, it is also used more broadly to refer to a variety of conditions resulting in unusually short stature in both children and adults.
Most cases of achondroplasia are associated with a dominant mutant form of the FGFR3 gene. Thus, if someone with achondroplasia has children with a person without achondr â¦ oplasia, 50% of the offspring would be predicted to inherit the disorder.f two people with achondroplasia were to have children, 50% would inherit acondroplasia (i.e. would be heterozygous for the mutant FGFR3 allele), 25% would be normal, and 25% would inherit two copies of the mutant FGFR3 allele, a condition which is almost certainly lethal.
