Living with Autosomal dominant lamellar ichthyosis

A rare inherited skin condition with large, dark scales and thick palms and soles, usually starting at birth.

Understanding Autosomal dominant lamellar ichthyosis

Autosomal dominant lamellar ichthyosis is a rare inherited skin disease that causes large, dark scales over most of the body.

It usually begins at birth or in the early newborn period. Scaling is often more noticeable on the arms and legs. The palms and soles are thickened (palmoplantar keratoderma). Some people have mild skin redness and moderate itching. In badly affected areas, people may not sweat, which can affect how the body handles heat.

GARD doesn't list a symptom list for this condition, but its summary describes these features:

  • Large, dark scales over most of the body

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
