Berardinelli-Seip congenital lipodystrophy in two siblings

Area of Science:

• Genetics
• Endocrinology
• Dermatology

Background:

• Berardinelli-Seip congenital lipodystrophy (BSCL) is a rare autosomal recessive disorder.
• It presents with lipoatrophy, hypertriglyceridemia, hepatomegaly, acanthosis nigricans, and acromegaloid features.
• BSCL type 2 (BSCL2) is more severe, with neonatal or early infancy onset, linked to chromosome 11q13.

Observation:

• This report details two siblings diagnosed with BSCL type 2.
• The siblings exhibited significant cutaneous manifestations.
• Observed dermatological signs included acanthosis nigricans, hypertrichosis, prominent subcutaneous veins, and increased lanugo hair.

Findings:

• The study focuses on the clinical presentation of BSCL type 2 in siblings.
• It highlights specific dermatological features associated with the condition.
• The genetic locus for BSCL2 on chromosome 11q13 is noted.

Implications:

• Early recognition of BSCL2 is crucial for timely intervention.
• Differentiating BSCL2 from other lipodystrophies enables appropriate management.
• Management strategies include lifestyle modifications and pharmacotherapy to prevent metabolic syndrome.
