ICD10 code of Congenital Generalized Lipodystrophy and ICD9 code

Congenital Generalized Lipodystrophy (CGL), also known as Berardinelli-Seip syndrome, is classified under ICD-10 code E88.1 (Lipodystrophy, not elsewhere classified). Historically, this rare condition was categorized under ICD-9 code 272.8, which covers other disorders of lipoid metabolism.

What is Congenital Generalized Lipodystrophy?

Congenital Generalized Lipodystrophy is an extremely rare genetic disorder characterized by a near-total absence of adipose tissue (body fat) from birth or early infancy. Because fat cells are essential for storing energy and regulating metabolism, individuals with Congenital Generalized Lipodystrophy often experience severe metabolic complications, including extreme insulin resistance, diabetes mellitus, and hypertriglyceridemia. With only four members currently in the DiseaseMaps.org community, we recognize how isolating this diagnosis can feel, but you are not alone in navigating these complex health challenges.

Is Congenital Generalized Lipodystrophy hereditary?

Yes, Congenital Generalized Lipodystrophy is an autosomal recessive disorder. This means that an individual must inherit two mutated copies of a specific gene—one from each parent—to manifest the condition. Several genes have been identified as causative, including:

• AGPAT2 (Type 1 CGL)


• BSCL2 (Type 2 CGL)


• CAV1 (Type 3 CGL)


• PTRF (Type 4 CGL)

How is Congenital Generalized Lipodystrophy diagnosed?

Diagnosis of Congenital Generalized Lipodystrophy is primarily clinical, based on the physical absence of subcutaneous fat, accelerated growth in childhood, and muscular hypertrophy. Confirmation is typically achieved through genetic testing to identify mutations in the genes listed above. Early diagnosis is vital to monitor for potential complications like hepatomegaly (enlarged liver) and cardiac arrhythmias associated with certain subtypes.

Next steps

• Consult an endocrinologist who specializes in rare metabolic or lipid disorders.


• Undergo genetic counseling to understand the inheritance pattern and implications for family members.


• Connect with the DiseaseMaps.org community to share experiences with others living with Congenital Generalized Lipodystrophy.


• Monitor metabolic markers frequently, including blood glucose, HbA1c, and triglyceride levels.
