Seipin is a protein that in humans is encoded by the BSCL2 gene.

Clinical significance

Mutations in BSCL2 are known to cause the following conditions:

• Congenital generalized lipodystrophy type 2;
• Spastic paraplegia 17, autosomal dominant (SPG17);
• Neuronopathy, distal hereditary motor, 5C (HMN5C);
• Encephalopathy, progressive, with or without lipodystrophy (PELD).
