Excerpted from the GeneReview: COMP-Related Pseudoachondroplasia
COMP-related pseudoachondroplasia (COMP-PSACH) is characterized by normal length at birth and normal facies. Often the presenting feature is a waddling gait, recognized at the onset of walking. Typically, the growth rate falls below the standard growth curve by approximately age two years, leading to a moderately severe form of disproportionate short-limb short stature. Joint pain during childhood, particularly in the large joints of the lower extremities, is common. Degenerative joint disease is progressive; approximately 50% of individuals with COMP-PSACH eventually require hip replacement surgery.
