    ### Response:
    Sjgren-Larsson syndrome is a condition characterized by dry, scaly skin (ichthyosis); neurological problems; and eye problems. These symptoms are apparent by early childhood and usually do not worsen with age.  Affected infants tend to be born prematurely. At birth the skin is red (erythema), but later in infancy the skin becomes dry, rough, and scaly with a brownish or yellowish tone.
