Achondroplasia is a form of short-limbed dwarfism. The word achondroplasia literally means “without cartilage formation.” Cartilage is a tough but flexible tissue that makes up much of the skeleton during early development. However, in achondroplasia the problem is not in forming cartilage but in converting it to bone (a process called ossification), particularly in the long bones of the arms and legs.
Achondroplasia is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. About 80 percent of people with achondroplasia have average-size parents; these cases result from new mutations in the FGFR3 gene. Read Here….

Can Dwarfs Have Normal Babies?
Two parents with dwarfism can have a child of average height because dwarfism is a dominant trait. And the parents probably did not inherit their dwarfism from their parents. At some point early in development, their FGFR3 gene picked up a DNA change that led to dwarfism.Read Here….
