Achondroplasia (ACH; MIM 100800) and hypochondroplasia (HCH; MIM 146000) are autosomal dominant disorders. ACH is caused by specific mutations in FGFR3. ACH represents the most common skeletal dysplasia in humans. It is characterized by rhizomelic dwarfism, trident hands and short fingers, midface hypoplasia with macrocephaly and frontal bossing. A small foramen magnum may cause generalized hypotonia, hyperreflexia or clonus in newborns.read more
