Chanarin-Dorfman Syndrome (CDS): A Rare Lipid Metabolism Disorder

Area of Science:

• Genetics and rare diseases
• Dermatology
• Pediatrics

Background:

• Chanarin-Dorfman syndrome (CDS) is an autosomal recessive disorder.
• It results from mutations in the comparative gene identification-58 (CGI-58) gene.
• CDS is characterized by ichthyosis and triglyceride accumulation in neutrophils.

Observation:

• A one-year-old boy presented with congenital skin peeling and abdominal distension.
• The patient exhibited ichthyosis, a hallmark dermatological sign of CDS.
• Developmental milestones were age-appropriately achieved.

Findings:

• Peripheral blood smear revealed vacuoles in neutrophils, indicative of triglyceride accumulation.
• Genetic testing confirmed heterozygous alleles in both parents, consistent with autosomal recessive inheritance.
• The case illustrates the clinical presentation of CDS in infancy.

Implications:

• Early diagnosis of CDS is crucial for appropriate management and genetic counseling.
• This case underscores the importance of recognizing ichthyosis and neutrophil abnormalities in diagnosing CDS.
• Further research into CGI-58 gene function may reveal therapeutic targets for lipid metabolism disorders.
