Sjögren-Larsson Syndrome: A Rare Presentation With Developmental Delay.

Area of Science:

• Genetics
• Biochemistry
• Dermatology

Background:

• Sjögren-Larsson syndrome (SLS) is a rare autosomal recessive disorder.
• It is characterized by spastic paralysis, ichthyosis, and intellectual disability.
• The underlying cause is deficient microsomal fatty aldehyde dehydrogenase (FALDH) activity.

Observation:

• A case study of an eight-year-old patient with SLS is presented.
• The patient exhibited classic symptoms including spastic diplegia, congenital ichthyosis, and intellectual disability.

Findings:

• FALDH deficiency leads to the accumulation of fatty aldehydes and alcohols.
• This accumulation is particularly noted in the skin, contributing to ichthyosis.
• The genetic basis involves autosomal recessive inheritance.

Implications:

• Early diagnosis of SLS is crucial for effective patient management.
• Genetic counseling is essential for affected families.
• Management strategies focus on skin care and supportive therapies.
