Lipodystrophy Due To Peptidic Growth Factors Deficiency
Deficiency of the peptidic growth factors is characterized by loss of subcutaneous fat layers on the limbs, lipodystrophy in the face and trunk and scleroderma-like skin disorders (thickened skin on the palms and soles and skin pigment changes on the limbs and trunk).
Also known as
combined insulin, insulin-like growth factor 1 (IGF1) and epidermal growth factor (EGF) deficiency; Hoepffner Dreyer Reimers syndrome; Hoepffner-Dreyer-Reimers syndrome; peptide growth factors deficiency; peptidic growth factors deficiency; Werner-like syndrome due to combined growth factor deficiency
Congenital Generalized Lipodystrophy
Autosomal recessive
An extremely rare autosomal recessive condition, characterized by an extreme scarcity of fat in the subcutaneous tissues.

Autosomal recessive
A lipodystrophy characterized by the association of lipoatrophy, hypertriglyceridemia, hepatomegaly and acromegaloid features. BSCL belongs to the group of extreme insulin resistance syndromes, which also includes leprechaunism, Rabson-Mendenhall syndrome, acquired generalized lipodystrophy, and types A and B insulin resistance.

- PPARG-associated congenital generalized lipodystrophy
Familial Partial Lipodystrophy
Includes the LMNA (Dunnigan), PPARG, PLIN1, LIPE, AKT2, CAV1 and PLAAT3 forms, which cause loss of fat from the limbs and buttocks with insulin resistance, diabetes, high triglycerides and fatty liver.
What a diagnosis changes
Knowing allows early screening and treatment of diabetes, triglycerides and liver disease, and in selected cases metreleptin.
Also known as
congenital partial lipodystrophy; FPLD; genetic partial lipodystrophy; lipodystrophy, familial partial
Specific forms also covered
Familial Partial Lipodystrophy, Dunnigan Type
Autosomal dominant
Familial Partial lipodystrophy, Dunnigan type (FPLD2) is a rare form of genetic lipodystrophy characterized by a loss of subcutaneous adipose tissue from the trunk, buttocks and limbs; fat accumulation in the neck, face, axillary and pelvic regions; muscular hypertrophy; and usually associated with metabolic complications such as insulin resistance, diabetes mellitus, dyslipidemia and liver steatosis.

Mandibuloacral Dysplasia
Autosomal recessive
Caused by variants in LMNA (type A) or ZMPSTE24 (type B), which cause underdevelopment of the jaw and collarbones, skin changes, fat loss and metabolic complications such as insulin resistance.
What a diagnosis changes
Knowing guides monitoring for diabetes, lipid and other complications.
Also known as

Multiple symmetric lipomatosis with partial lipodystrophy (MFN2)
Autosomal recessive
Large fatty deposits on the neck and upper body with loss of fat elsewhere, caused by biallelic MFN2 variants.
