Say Barber Miller syndrome

Title

Other Names:

Microcephaly hypogammaglobulinemia abnormal immunity; Microcephaly with chemotactic defect and transient hypogammaglobulinemia

Categories:

Congenital and Genetic Diseases; Immune System Diseases; Nervous System Diseases

Summary Summary

The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.

Orpha Number: 3132

Definition

Say-Barber-Miller syndrome is characterised by the association of unusual facial features, microcephaly, developmental delay, and severe postnatal growth retardation.

Epidemiology

It has been reported in two brothers born to normal parents.

Clinical description

Additional features include hypogonadism, flexion contractures, hypoplastic patellae, scoliosis, eczema and recurrent infections. The characteristic facies was marked by a sloping forehead, beaked nose, large and protruding ears, and micrognathia. Low levels of serum gammaglobulins and defective chemotaxis were detected in both boys during infancy.

Prognosis

The hypogammaglobulinaemia improved with age but the defective chemotaxis and recurrent infections persisted.

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.
