What is the cause of Harlequin ichthyosis?
Harlequin ichthyosis is caused by mutations in the ABCA12 gene. This gene provides instructions for making a protein that is essential for the normal development of skin cells. This protein plays a major role in the transport of fats (lipids) in the outermost layer of skin (the epidermis).
Is Harlequin ichthyosis autosomal recessive?
Harlequin ichthyosis 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. [1]

What are the causes of harlequin ichthyosis?
Mutations in the ABCA12 gene cause harlequin ichthyosis. The ABCA12 gene provides instructions for making a protein that is essential for the normal development of skin cells. This protein plays a major role in the transport of fats (lipids) in the outermost layer of skin (the epidermis). Some mutations in the ABCA12 gene prevent the cell from making any ABCA12 protein. Other mutations lead to the production of an abnormally small version of the protein that cannot transport lipids properly. A loss of functional ABCA12 protein disrupts the normal development of the epidermis, resulting in the hard, thick scales characteristic of harlequin ichthyosis.
Why do babies with Harlequin ichthyosis need immediate intensive care?
Newborns with Harlequin ichthyosis need immediate intensive care because of difficulty in breathing and eating.
How does Harlequin ichthyosis affect the body?
The skin normally forms a protective barrier between the body and its surrounding environment. The skin abnormalities associated with harlequin ichthyosis disrupt this barrier, making it more difficult for affected infants to control water loss, regulate their body temperature, and fight infections. Infants with harlequin ichthyosis often experience an excessive loss of fluids (dehydration) and develop life-threatening infections in the first few weeks of life. It used to be very rare for affected infants to survive the newborn period. However, with intensive medical support and improved treatment, people with this disorder now have a better chance of living into childhood and adolescence.

Diagnosis of Harlequin syndrome is based on observing symptoms consistent with the syndrome, followed by a series of tests to rule out other diseases associated with Harlequin sign.
