Summary Summary

Nablus mask-like facial syndrome is a rare microdeletion syndrome that is characterized by a mask-like facial appearance. Facial features include narrowing of the eye opening (blepharophimosis); tight appearing glistening facial skin; and flat and broad nose. Other features include malformed ears; unusual scalp hair pattern; permanently bent fingers and toes (camptodactyly); joint deformities (contractures) that restrict movement in the hands and feet; unusual dentition; mild developmental delay; undescended testicles in males (cryptorchidism); and a happy disposition. This condition is caused by a deletion at chromosome 8q22.1.^[1]

Symptoms Symptoms

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.
