Inheritance

--Achondroplasia is the result of a new mutation in the FGFR3 gene. It is Inherited through an Autosomal dominant pattern. Meaning that only one faulty gene is needed to express the gene. 80% of achondroplasia cases involve two normal parents giving birth to an affected child because of a new mutation that occurs during meiosis this. The new mutation occurs in every 15,000-40,000 live births in a population.
