Sjögren-Larsson Syndrome: A Rare Presentation With Developmental Delay

Abstract

Sjögren-Larsson syndrome (SLS) is a rare, inherited disorder passed down through families in an autosomal recessive pattern. Its main characteristics are spastic diplegic paralysis, congenital ichthyotic hyperkeratosis, and mild-to-moderate mental retardation. Lack of activity of microsomal fatty aldehyde dehydrogenase (FALDH) or its complete absence is the primary cause of this syndrome, leading to the build-up of fatty aldehydes and fatty alcohols in the body, particularly in the skin. In order to provide the best care for patients, educating them about the management of dry skin and offering genetic counseling are essential. We hereby present a case of an eight-year-old patient with spastic diplegia, congenital ichthyosis, and intellectual disability diagnosed with SLS.
