RBPJ gene

recombination signal binding protein for immunoglobulin kappa J region

Normal Function

The RBPJ gene provides instructions for making a protein called RBP-J, which is an integral part of a signaling pathway known as the Notch pathway. Notch signaling controls how certain types of cells develop in the growing embryo, including those that form the bones, heart, muscles, nerves, and blood. Signaling through the Notch pathway stimulates the RBP-J protein to attach (bind) to specific regions of DNA and control the activity of genes that play a role in cellular development.

Health Conditions Related to Genetic Changes

Adams-Oliver syndrome

Mutations in the RBPJ gene lead to Adams-Oliver syndrome, a condition characterized by areas of missing skin (aplasia cutis congenita), usually on the scalp, and malformations of the hands and feet. These mutations change single protein building blocks in the RBP-J protein, altering the region of the protein that normally binds to DNA. The altered proteins are unable to bind to DNA, preventing the activation of particular genes. These changes in gene activity impair the proper development of the skin on the top of the head and the bones in the hands and feet. It is unclear why impaired development primarily affects these tissues.
