All people with achondroplasia have short stature. The average height of an adult male with achondroplasia is 131 centimeters (4 feet, 4 inches), and the average height for adult females is 124 centimeters (4 feet, 1 inch).bout 80 percent of people with achondroplasia have average-size parents; these cases result from new mutations in the FGFR3 gene. In the remaining cases, people with achondroplasia have inherited an altered FGFR3 gene from one or two affected parents.
Hint: Fill in the punnitt square: ...remember that this is a dominant disorder...anyone with one A allele will have a dwarf phenotype... YES, they can have a child without achondroplasia (aa) - of 'normal' height and stature (lower right box - aa) 25% chance. They have a 50% chance of a child with a dwarf phenotype Aa, and any child conceived with the AA genotype will die in utero.
