Summary Summary

Gomez Lopez Hernandez syndrome (GLHS) is a rare condition characterized by partial scalp baldness (alopecia); numbness of the face, eyes, sinuses, and mouth (trigeminal anesthesia); and a brain abnormality called rhombencephalosynapsis. Additional symptoms vary but may include distinctive facial features, intellectual disability or other neurological problems, and craniofacial abnormalities. The cause of GLHS is poorly understood. It may be genetic, possibly with autosomal recessive inheritance. Treatment depends on the signs and symptoms present in each person.^[1]^[2]^[3]

Symptoms Symptoms

Gomez Lopez Hernandez syndrome is primarily characterized by:^[1]^[2]

Rhombencephalosynapsis - partial or total absence of the cerebellar vermis (the area between the two cerebellar hemispheres) and fusion of the hemispheres
Trigeminal anesthesia - a neurological disorder that causes numbness of the face, eyes, sinuses, and mouth
Scalp alopecia - partial or complete hair loss

Other signs and symptoms vary but may include:^[1]^[2]

Poor muscle tone (hypotonia)
Ataxia
Behavioral abnormalities
Intellectual disability
Developmental delay
Craniofacial abnormalities
Seizures
Corneal opacities (clouding of the clear front covering of the eye)
Short stature
Distinctive facial features (i.e. wide-spaced eyes and low-set, posteriorly rotated ears)

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.

Cause Cause

The cause of Gomez Lopez Hernandez syndrome (GLHS) currently is unknown. While it occurs sporadically, researchers have suspected that it has a genetic basis.^[4] However, no specific gene mutations or chromosome abnormalities that cause GLHS have been identified yet.^[4] Three cases have been associated with consanguinity (when parents are related), suggesting the possibility of autosomal recessive inheritance.^[3]^[4] Further studies need to be performed to find the underlying cause of GLHS.^[3]

Treatment Treatment

The resources below provide information about treatment options for this condition. If you have questions about which treatment is right for you, talk to your healthcare professional.

Management Guidelines

Project OrphanAnesthesia is a project whose aim is to create peer-reviewed, readily accessible guidelines for patients with rare diseases and for the anesthesiologists caring for them. The project is a collaborative effort of the German Society of Anesthesiology and Intensive Care, Orphanet, the European Society of Pediatric Anesthesia, anesthetists and rare disease experts with the aim to contribute to patient safety.

Find a Specialist Find a Specialist

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.
