Rare autosomal recessive syndrome of extreme insulin resistance due to mutations in the binding domain of INSULIN RECEPTOR. Clinical features include severe intrauterine and postnatal growth restriction, characteristic dysmorphic FACIES; HIRSUTISM; VIRILIZATION; multiple endocrine abnormalities, and early death.

Rare autosomal recessive syndrome of extreme insulin resistance due to mutations in the binding domain of INSULIN RECEPTOR. Clinical features include severe intrauterine and postnatal growth restriction, characteristic dysmorphic FACIES; HIRSUTISM; VIRILIZATION; multiple endocrine abnormalities, and early death.
Rare autosomal recessive syndrome, characterized by a milder set of clinical features with prolonged survival, compared to Donohue syndrome. Mutations in the same INSULIN RECEPTOR, mostly in the non-binding domain, result in Rabson-Mendenhall syndrome (allelic heterogeneity). Clinical features include insulin-resistant DIABETES MELLITUS, often with ACANTHOSIS NIGRICANS; DIABETIC KETOACIDOSIS; HYPERTRICHOSIS; and dysmorphisms.
