Question: What is (are) Lamellar ichthyosis ?
Answer: Lamellar ichthyosis is a rare genetic condition that affects the skin. Infants affected by lamellar ichthyosis are generally born with a shiny, waxy layer of skin (called a collodian membrane) that is typically shed within the first two weeks of life. The skin beneath the collodian membrane is red and scaly. Other signs and symptoms of the condition may include ectropion, lips that turn outwards, hair loss, palmoplantar hyperkeratosis (thick skin on the palms of the hands and/or soles of the feet), nail abnormalities, dehydration and respiratory problems. Although the condition may be caused by changes (mutations) in one of several different genes, approximately 90% of cases are caused by mutations in the TGM1 gene. Lamellar ichthyosis is generally inherited in an autosomal recessive manner. Treatment is based on the signs and symptoms present in each person.
