What is Clouston Syndrome?
Clouston Syndrome, also referred to as Hidrotic Ectodermal Dysplasia 2 (HED2), is a genetic condition characterized by anomalies in the skin, hair, and nails. It is caused by mutations in the GJB6 gene, which provides instructions for making a protein called connexin 30. This protein is crucial for the function of gap junctions, which are channels that allow communication between cells.
Clouston Syndrome Types
While Clouston Syndrome is a unique condition, it falls under the broader category of ectodermal dysplasias. These disorders vary in their manifestations but share common features related to the ectodermal structures.
Causes and Genetic Basis
Clouston Syndrome is inherited in an autosomal dominant pattern, meaning one copy of the altered gene in each cell is sufficient to cause the disorder. The mutations in the GJB6 gene disrupt the function of connexin 30, impairing cell communication and leading to the symptoms observed in the condition.

Symptoms of Clouston Syndrome
Recognizing the symptoms of Clouston Syndrome is essential for early intervention and management. The condition primarily affects the integumentary system, leading to a distinctive set of clinical features.
Hair Abnormalities
Individuals with Clouston Syndrome often experience hair abnormalities, such as:
- Alopecia: Partial or complete absence of hair on the scalp and, sometimes, the body.
- Sparse hair growth: Hair that is thin, brittle, and slow-growing.
- Texture changes: Hair that may be wiry or coarse.
Nail Dystrophy
Nail abnormalities are a hallmark of Clouston Syndrome and may include:
- Thickened nails: Nails may become unusually thick and discoloured.
- Nail deformities: This can consist of splitting, ridging, or clubbing of the nails.
Skin Anomalies
The skin manifestations of Clouston Syndrome are varied:
- Palmoplantar hyperkeratosis: Thickening of the skin on the palms and soles.
- Hyperpigmentation: Darkening of some regions of the skin.
- Decreased sweating: Reduced ability to sweat, leading to heat intolerance.

Get Second OpinionDiagnosing Clouston Syndrome
Diagnosis of Clouston Syndrome involves a combination of clinical evaluation, family history assessment, and genetic testing.
Clinical Evaluation
A thorough physical examination can reveal the characteristic features of Clouston Syndrome, such as hair and nail anomalies.
Genetic Testing
Genetic testing confirms the diagnosis by identifying mutations in the GJB6 gene. This can also help in distinguishing Clouston Syndrome from other forms of ectodermal dysplasia.
Treatment and Management
While there is no cure for Clouston Syndrome, several strategies can help manage its symptoms and improve quality of life.
Dermatological Care
- Moisturizers and emollients: Regular use can help manage skin dryness and hyperkeratosis.
- Keratolytic agents: These can be used to reduce thickened skin on the palms and soles.
Hair and Nail Care
- Gentle hair care products: To minimize further hair damage.
- Nail treatments: Regular trimming and care can help manage nail dystrophy.
Medical Interventions
- Topical treatments: For specific skin issues, such as hyperpigmentation or keratosis.
- Systemic medications: In some cases, medications may be prescribed to address severe skin or nail issues.
Genetic Counseling
Genetic counseling is recommended for affected individuals and their families to understand the inheritance pattern and risks to future generations.
