Berardinelli-Seip syndrome is a rare genetic disease present from birth. The body is born with almost no fat tissue under the skin or around organs. Because fat tissue is missing, fat gets stored in other places like the liver and muscles. This causes big health problems such as very high blood fats, insulin resistance, fatty liver, and diabetes in the teen years. The heart can also become thick and weak, and many patients have very strong muscles and a muscular look because fat is absent. Doctors diagnose it by the typical look, blood tests, and genetic testing. It is inherited in an autosomal recessive way. NCBI+2NCBI+2

Berardinelli–Seip syndrome is a rare, inherited condition in which a person is born with almost no body fat. Because fat cells are missing, fat builds up in the liver and muscles. This causes insulin resistance, very high triglycerides, fatty liver, enlarged liver, and diabetes in many teens and adults. It is autosomal recessive and usually recognized at birth or early childhood. The main approved medicine that targets the core problem (leptin deficiency) is metreleptin. Most other treatments manage diabetes, triglycerides, and liver disease. NCBI+2NCBI+2

Because there are almost no working fat cells, the hormone leptin is very low. Low leptin and lack of safe fat “storage space” make sugar and fat levels rise in the blood. The liver becomes large because of fat build-up (hepatic steatosis). Over time the liver can scar (cirrhosis). The mix of insulin resistance, high triglycerides, and fatty liver often appears in childhood and gets worse with age. NCBI+1

Many children with this syndrome have acanthosis nigricans (dark, thick skin folds), enlarged liver, and “acromegaloid” features such as prominent jaw, big hands and feet, and visible veins and muscles. Some have learning difficulties, bone cysts, or early puberty in girls. Heart muscle thickening (hypertrophic cardiomyopathy) happens in a notable group and can cause early heart problems. NCBI


Other names

Doctors use several names for the same condition. Common synonyms include Berardinelli-Seip congenital lipodystrophy, congenital generalized lipodystrophy (CGL), Seip syndrome, total lipodystrophy, and older terms like lipoatrophic diabetes when diabetes develops. A historical term, Brunzell syndrome, refers to lipoatrophy with bone cysts and is now recognized as part of this condition. NCBI


Types

There are four main genetic subtypes. Type 1 (CGL1) is due to mutations in AGPAT2, a gene that helps make triglycerides and phospholipids. Type 2 (CGL2) is due to mutations in BSCL2 (seipin), a protein needed for forming normal fat cells. Type 3 (CGL3) involves CAV1 (caveolin-1), and Type 4 (CGL4) involves CAVIN1 (also called PTRF), both important for small membrane “pits” called caveolae. Together, these gene defects stop fat cells from forming or working, so fat cannot be stored properly. PMC

Types 1 and 2 are the most common worldwide. People with BSCL2 variants more often have learning difficulties than those with AGPAT2 variants. CAVIN1-related cases may have muscle problems and heart rhythm issues. Genetic testing confirms the exact subtype and helps guide screening for heart and liver problems in follow-up care. NCBI


Causes

  1. AGPAT2 gene mutations stop normal triglyceride and membrane lipid formation in fat cells, so fat cells cannot store fat. PMC

  2. BSCL2 (seipin) mutations disrupt fat-cell development and lipid droplet formation, so adipose tissue fails to develop. PMC

  3. CAV1 mutations alter caveolae in cell membranes, which are needed for fat-cell signaling and lipid handling. PMC

  4. CAVIN1 (PTRF) mutations destabilize caveolae and caveolin proteins and can cause muscle and heart rhythm problems along with lipodystrophy. NCBI

  5. Autosomal recessive inheritance means a child gets one faulty copy from each parent; carriers usually have no symptoms. NCBI

  6. Failure of adipogenesis (new fat cell formation) is a core biological cause across subtypes. PMC

  7. Defective lipid droplet biogenesis leads to poor fat storage inside fat cells. Orpha.net

  8. Leptin deficiency from lack of fat tissue drives severe insulin resistance and high triglycerides. NCBI

  9. Ectopic fat deposition in liver and muscle harms those organs and worsens metabolic disease. NCBI

  10. Hormonal imbalance (such as high insulin levels) starts early because the body cannot buffer nutrients in fat tissue. NCBI

  11. High triglyceride production by the liver occurs when fat cannot be safely stored in adipose tissue. OUP Academic

  12. Early life onset (even at birth) means problems accumulate over time. NCBI

  13. Founder mutations in certain regions (for example parts of the Middle East or Portugal) increase local cases. NCBI

  14. Genotype–phenotype effects (e.g., BSCL2 and cognition; CAVIN1 and arrhythmia) shape individual features. NCBI

  15. Bone effects like cysts relate to the disease biology (seen especially with AGPAT2). NCBI

  16. Muscle hypertrophy happens because lipid accumulates in muscle and fat is absent elsewhere. NCBI

  17. Heart muscle thickening can develop from disease biology and metabolic stress. NCBI

  18. Liver steatosis and later fibrosis are caused by long-term ectopic fat and inflammation. NCBI

  19. Severe insulin resistance evolves into diabetes in many teens and young adults. NCBI

  20. Metabolic stress without adipose “buffering” underlies the full syndrome across all types. OUP Academic


Symptoms and signs

1) Generalized loss of fat (lipoatrophy). The whole body lacks fat: face, arms, legs, and trunk. The lack is obvious soon after birth or in early infancy. This is the hallmark feature. NCBI

2) Muscular appearance and visible veins. Because subcutaneous fat is missing, muscles and veins look prominent, giving a very athletic look even in children. Endocrinology Society

3) Acanthosis nigricans. Dark, velvety skin in the neck, armpits, or groin shows high insulin levels and insulin resistance. It may appear early in life. NCBI

4) Enlarged liver (hepatomegaly). Fat builds up in the liver and makes it large, which can progress to scarring later in life. NCBI

5) Very high triglycerides. Blood triglycerides can be extremely high, sometimes with high cholesterol, due to the body’s inability to store fat in adipose tissue. NCBI

6) Insulin resistance and diabetes. Many patients develop diabetes between ages 15 and 20, and glucose can be hard to control. Symptoms include thirst, frequent urination, and weight loss. NCBI

7) Acromegaloid features. Some children have a prominent jaw, large hands and feet, and other “acromegaly-like” traits, even though they do not have excess growth hormone. NCBI

8) Heart problems. A significant group develop thick heart muscle (hypertrophic cardiomyopathy). This can cause heart failure and early death if not monitored. NCBI

9) Learning difficulties. Mild to moderate intellectual impairment is more common in people with BSCL2 variants than AGPAT2 variants, but not everyone is affected. NCBI

10) Bone cysts. Some patients develop cysts in long bones (often in the teen years), more often in AGPAT2 disease. These are seen on X-rays. NCBI

11) Precocious puberty in girls. A few girls start puberty early (before age seven), with changes in body hair and menses patterns. NCBI

12) Hirsutism and hypertrichosis. Extra hair growth and low hairline may occur and do not always relate to hormones. NCBI

13) Enlarged external genitalia in boys; clitoromegaly in girls. These are part of the acromegaloid pattern in some children. NCBI

14) Liver complications over time. Without treatment, fatty liver can progress to fibrosis and cirrhosis, so long-term monitoring is needed. NCBI

15) Muscle hypertrophy and high strength appearance. Muscles may look big because fat is missing and lipid is stored in muscle, although true muscle strength varies. NCBI


Diagnostic tests

A) Physical examination (bedside checks)

1) Whole-body fat loss pattern. The doctor looks for generalized loss of fat in the face, arms, legs, and trunk with a muscular look. This is the key sign that raises suspicion for CGL. NCBI

2) Skin inspection for acanthosis. Dark, thick skin in folds suggests severe insulin resistance and supports the diagnosis. NCBI

3) Abdominal exam for hepatomegaly. Palpating the abdomen can reveal a large liver from fatty infiltration and guides further imaging. NCBI

4) Growth and “acromegaloid” features. Checking hands, feet, jaw, and facial bones for enlargement helps document typical features. NCBI

5) Puberty staging and hair pattern. Early puberty in girls and excess hair growth are noted during routine exam and recorded for follow-up. NCBI

B) “Manual/bedside” measurements

6) Skinfold thickness measurements. Calipers show extremely thin or absent skinfolds in many body sites, verifying generalized lipoatrophy at the bedside. Clinical tools like this help document fat loss before imaging. OUP Academic

7) Waist, hip, and limb circumferences. Simple tape measurements track the unusual body composition (low fat, apparent muscle bulk) over time. They support clinical judgment and help in follow-up. OUP Academic

8) Blood pressure and acanthosis scoring. Routine vitals and simple skin scoring reflect insulin resistance and cardiovascular risk, and they are recommended in regular check-ups. OUP Academic

9) Hand-grip or functional muscle checks. Quick strength checks and observation of muscle bulk are helpful because muscle looks large in this condition. They guide whether to order muscle studies if weakness is suspected. OUP Academic

10) Family history and pedigree. Because inheritance is autosomal recessive, a careful pedigree and inquiry about consanguinity help risk assessment and genetic counseling. NCBI

C) Laboratory and pathological tests

11) Fasting lipid panel. Triglycerides are often very high. Treating high triglycerides is essential to lower pancreatitis and heart risk. NCBI

12) Glucose and HbA1c tests. Fasting glucose, a 2-hour oral glucose tolerance test, and HbA1c detect early diabetes and guide treatment. Screening is recommended at least yearly. PubMed

13) Fasting insulin and C-peptide. These often run high and show insulin resistance even before diabetes develops. NCBI

14) Liver enzymes and synthetic function. ALT, AST, bilirubin, albumin, and INR check for fatty liver, inflammation, and scarring. Regular monitoring is advised due to steatosis risk. NCBI

15) Serum leptin. Levels are usually very low because fat tissue is absent; low leptin supports the diagnosis and can help identify patients who may benefit from leptin therapy. NCBI

16) Creatine kinase (CK). CK can be elevated in some patients, especially with CAVIN1 disease, and points to muscle involvement. NCBI

17) Genetic testing panel. Sequencing AGPAT2, BSCL2, CAV1, and CAVIN1 (PTRF) confirms the subtype and helps with family counseling. Testing is a core part of diagnosis today. NCBI+1

18) Liver biopsy (select cases). Biopsy is not routine but may be used when diagnosis is unclear or to stage liver disease; it shows fatty change and, in advanced cases, fibrosis. OUP Academic

D) Electrodiagnostic tests

19) Electrocardiogram (ECG) and 24-hour Holter. These detect heart rhythm problems seen in some patients (particularly with CAVIN1). Regular cardiac screening is recommended. NCBI

20) Electromyography (EMG) and nerve conduction studies (when indicated). If muscle weakness or myopathy is suspected, EMG/NCS help document muscle involvement linked to caveolae pathway disease. NCBI

E) Imaging tests (often part of routine care)

Body MRI or DXA for fat distribution confirms near-total fat absence and helps distinguish generalized from partial lipodystrophy. Liver ultrasound (and sometimes elastography) checks for fatty liver and scarring. Echocardiography looks for heart muscle thickening. Bone X-rays can show cysts in long bones. These studies support the diagnosis and guide monitoring. Seep+1

Non-pharmacological treatments (therapies & other supports)

Below are practical, clinic-ready actions. For each item I state the description → purpose → mechanism in one short paragraph.

  1. Structured low-fat meal pattern with controlled carbohydrates → Goal: lower triglycerides and reduce fatty liver and pancreatitis risk. → How it helps: keeping total fat low (often <15% of calories in severe hypertriglyceridemia) and avoiding large sugar loads reduces chylomicron/TG spikes and liver fat. Pair each meal with fiber and protein. endotext.org+1

  2. Replace some long-chain fats with MCT oil → Goal: provide calories without raising triglycerides as much. → How it helps: medium-chain triglycerides are absorbed and oxidized more quickly and are less chylomicron-dependent, which may blunt post-meal TG rises. endocrinolrespract.org

  3. Consistent carbohydrate distribution → Goal: smoother blood sugars and less insulin surge. → How it helps: smaller, regular carb portions reduce hepatic fat flux and insulin resistance stress. CloudFront

  4. Dietary fructose caution → Goal: protect the liver. → How it helps: limiting sugar-sweetened drinks and concentrated fructose lowers de-novo lipogenesis and hepatic steatosis burden. CloudFront

  5. Daily physical activity (aerobic + resistance) → Goal: improve insulin sensitivity and triglycerides. → How it helps: muscle contraction increases glucose uptake independent of insulin and raises fatty-acid oxidation. CloudFront

  6. Weight-neutral energy planning → Goal: adequate growth in children and stable energy in adults without excess fat intake. → How it helps: careful calorie planning meets needs while avoiding TG spikes from high-fat/high-sugar foods. CloudFront

  13. Dental and sleep hygiene → Goal: reduce systemic inflammation that can worsen metabolic control. → How it helps: treats apnea and gum disease, which may aggravate insulin resistance. CloudFront

  14. Illness/surgery sick-day rules → Goal: avoid severe hyperglycemia or TG spikes. → How it helps: pre-planned adjustments in carbs/insulin and hydration. CloudFront

  15. Education on warning signs (abdominal pain, nausea, vomiting) → Goal: fast action for pancreatitis. → How it helps: early ER presentation lowers complications. endotext.org

  16. Vitamin and micronutrient adequacy → Goal: meet needs with low-fat pattern. → How it helps: guided use of fat-soluble vitamins where intake is limited. CloudFront

  17. Psychosocial support → Goal: body-image and rare-disease stress coping. → How it helps: counseling improves adherence and quality of life. National Organization for Rare Disorders

  18. School/work care plans → Goal: safe meals and activity. → How it helps: written plans prevent high-TG snacks and support activity time. National Organization for Rare Disorders

  19. Immunization up to date (esp. hepatitis A/B, influenza) → Goal: reduce infections that can destabilize metabolism. → How it helps: fewer inflammatory flares and liver hits. CloudFront

  20. Regular liver imaging and fibrosis assessment → Goal: catch steatohepatitis/cirrhosis early. → How it helps: ultrasound/elastography trend guides escalation (including transplant evaluation). CloudFront

Frequently asked questions (FAQ)

1) Is there a cure?
No cure yet. The only targeted therapy is metreleptin for generalized lipodystrophy. The rest manage diabetes, triglycerides, and liver disease. FDA Access Data

2) Why do I have diabetes without body fat?
Because fat cells are missing, fat “spills” into muscle and liver, causing severe insulin resistance and high sugars. NCBI

3) Why are my triglycerides so high?
Without adipose storage, circulating TGs rise, especially after meals. Very high TGs can cause pancreatitis. NCBI+1

4) Can diet really help?
Yes. A low-fat, controlled-carb pattern and MCT substitution can lower TGs and ease liver fat. endotext.org+1

5) Do I always need insulin?
Many people need insulin at some point. Choice depends on your A1c, glucose patterns, and response to metreleptin and other agents. FDA Access Data

6) What does metreleptin do?
It replaces the missing leptin hormone, improving appetite control, insulin sensitivity, glucose, and triglycerides in generalized lipodystrophy. FDA Access Data

7) Are there risks with metreleptin?
Yes. Neutralizing antibodies, autoimmune problems, and a lymphoma signal have been reported; careful REMS monitoring is required. FDA Access Data

8) Which pill lowers triglycerides fastest?
Fibrates and prescription omega-3 fatty acids are standard for severe TG reduction; both need lab monitoring and clinician guidance. FDA Access Data+1

9) Should I take a statin?
If your LDL-C or overall ASCVD risk is high, a statin is often recommended in addition to TG therapy. FDA Access Data

10) Will GLP-1 or SGLT2 help me?
They help many with diabetes and may aid weight, liver, heart, and kidney outcomes, even though they don’t treat leptin deficiency directly. FDA Access Data+1

11) Can I drink alcohol?
Best to avoid, to protect your liver. CloudFront

12) Will I need liver surgery or transplant?
Only a minority progress to advanced cirrhosis; transplant is for end-stage disease after full medical therapy. CloudFront

13) Can exercise replace medicines?
Exercise helps a lot, but most people still need medications or metreleptin. CloudFront

14) What about pregnancy?
Plan ahead with a high-risk team; some drugs (ACEI/ARB, statins) are not safe in pregnancy. FDA Access Data

15) Where can I find expert care?
Ask for referral to a rare-disease center or lipodystrophy clinic; telehealth links may help if none are nearby. Genetic Rare Diseases Center
