What is the difference between achondroplasia and hypochondroplasia?

Compared to those who have achondroplasia, those with hypochondroplasia have less height difference. They are usually between 46 to 63 inches tall. They have less pronounced midface features, and limbs are shorter than the trunk, but it is not as obvious as in achondroplasia.

What are the symptoms of hypochondroplasia?

Signs & Symptoms Hypochondroplasia is primarily characterized by small stature, disproportionately short arms and legs (limbs), mild to moderate shortness of the fingers and toes (brachydactyly), and broad, short hands and feet (i.e., short-limbed dwarfism).

Is there a cure for hypochondroplasia?

Hypochondroplasia is transmitted as an autosomal dominant trait affecting the FGFR3 gene on chromosome 4p16.3. There is currently no cure for this condition.

Is hypochondroplasia a skeletal dysplasia?
