Dubowitz syndrome: a cholesterol metabolism disorder?

Area of Science:

• Genetics
• Developmental Biology
• Pediatrics

Background:

• Dubowitz syndrome (DS) is a rare genetic disorder characterized by multiple congenital anomalies.
• Key features include growth failure, distinctive facial morphology, microcephaly, mild intellectual disability, and eczema in over 50% of cases.
• The disorder exhibits significant variability in clinical expression and affects multiple organ systems.

Observation:

• This report details a male Turkish patient presenting with typical and less common manifestations of Dubowitz syndrome.
• The patient exhibited persistently low serum lipid levels, a finding noted in only one prior case.
• Additionally, the patient had an arachnoid cyst, an uncommon comorbidity in DS.

Findings:

• The case expands the known clinical spectrum of Dubowitz syndrome.
• It underscores the association between DS and dyslipidemia, specifically persistent hypocholesterolemia.
• The presence of an arachnoid cyst in this DS patient suggests potential neurological involvement or a broader phenotypic association.

Implications:

• This case contributes to understanding the complex and variable phenotype of Dubowitz syndrome.
• Further research into the genetic and metabolic underpinnings of DS may reveal links to lipid metabolism.
• Recognizing these rarer associations can aid in comprehensive patient management and diagnosis.
