Hairy elbows, short stature, facial dysmorphism, and developmental delay; Wiedemann Grosse Dibbern syndrome; WDSTS; Hairy elbows, short stature, facial dysmorphism, and developmental delay; Wiedemann Grosse Dibbern syndrome; WDSTS; Hypertrichosis-short stature-facial dysmorphism-developmental delay syndrome See More

Summary Summary

Wiedemann-Steiner syndrome is a rare genetic condition characterized by distinctive facial features, hairy elbows, short stature, and intellectual disability. ^[1]^[2]^[3] This condition is caused by changes (mutations) in the KMT2A gene (also known as the MLL gene). It is inherited in an autosomal dominant manner. Most cases result from new (de novo) mutations that occur only in an egg or sperm cell, or just after conception.^[4] Treatment is symptomatic and supportive and may include special education classes and speech and occupational therapies aimed at increasing motor functioning and language.^[5]

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.
