[Sjögren-Larsson syndrome: Pediatric case report].

Area of Science:

• Biochemistry
• Genetics
• Dermatology

Background:

• Sjogren-Larsson syndrome is a rare genetic disorder.
• It is characterized by congenital ichthyosis, intellectual disability, and spasticity.
• The primary defect involves mutations in the ALDH3A2 gene, leading to fatty aldehyde dehydrogenase deficiency.

Observation:

• This case report focuses on diagnosing a patient presenting with Sjogren-Larsson syndrome symptoms.
• Diagnosis was confirmed via quantification of enzymatic activity in cultured fibroblasts.
• Family members, including parents and a brother with suggestive symptoms, were also evaluated.

Findings:

• Enzyme activity quantification in fibroblasts confirmed Sjogren-Larsson syndrome.
• The study highlights the utility of enzymatic assays for diagnosing this condition.
• Genetic analysis of the ALDH3A2 gene is crucial for understanding the underlying defect.

Implications:

• Accurate diagnosis of Sjogren-Larsson syndrome is essential for appropriate patient management.
• Enzyme activity assays provide a reliable diagnostic method.
• Understanding the genetic basis aids in family screening and genetic counseling.
