Question: What is (are) nonbullous congenital ichthyosiform erythroderma ?
Answer: Nonbullous congenital ichthyosiform erythroderma (NBCIE) is a condition that mainly affects the skin. Some affected infants are born with a tight, clear sheath covering their skin called a collodion membrane. This membrane is usually shed during the first few weeks of life. Individuals with NBCIE have skin that is red (erythema) and covered with fine white scales. Some people with NBCIE have outward turning eyelids and lips, a thickening of the skin on the palms and soles of the feet (keratoderma), and nails that do not grow normally (nail dystrophy). Infants with NBCIE may develop infections, an excessive loss of fluids (dehydration), and respiratory problems early in life.

Question: How many people are affected by nonbullous congenital ichthyosiform erythroderma ?
Answer: NBCIE is estimated to affect 1 in 200,000 to 300,000 individuals in the United States. This condition is more common in Norway, where an estimated 1 in 90,000 people are affected.

Question: What are the genetic changes related to nonbullous congenital ichthyosiform erythroderma ?
Answer: Mutations in at least three genes can cause NBCIE. These genes provide instructions for making proteins that are found in the outermost layer of the skin (the epidermis). The epidermis forms a protective barrier between the body and its surrounding environment. The skin abnormalities associated with NBCIE disrupt this protective barrier, making it more difficult for affected infants to control water loss, regulate body temperature, and fight infections. Mutations in the ALOX12B and ALOXE3 genes are responsible for the majority of cases of NBCIE. Mutations in one other gene associated with this condition are found in only a small percentage of cases. In some people with NBCIE, the cause of the disorder is unknown. Researchers are looking for additional genes that are associated with NBCIE.

Question: Is nonbullous congenital ichthyosiform erythroderma inherited ?
Answer: This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
