The clinical course of an autopsied Morquio A syndrome patient.

The catalogued case depicts the characteristic skeletal deformities present in patients with Morquio syndrome with hyperlaxity of joints, pectus carinatum, and genu valgum (knock-knee). The patient displayed noticeable short stature with pectus carinatum at age 2, genu valgum at age 5, stopped growing around the age of 5 (height: 86.4 cm; body weight: 19 kg at 18 years old) as well as hyperlaxity of joints. His posture (the look up at the sky position) seen at ages 21 and 23 is typical of Morquio patients to ease breathing.
