Definition
Facial dysmorphism-shawl scrotum-joint laxity syndrome is characterised by facial dysmorphism (hypertelorism, telecanthus, downslanting palpebral fissures, ptosis, malar hypoplasia, broad nasal bridge, thin upper lip, smooth philtrum, and low-set prominent ears) and associated with joint anomalies (genu valgum or cubitus valgus, hyper-extensible joints, etc.). It has been described in two patients (a mother and her son). The boy also had hypoplastic shawl scrotum and cryptorchidism, and the mother had mild intellectual deficit.

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
