Liberfarb syndrome (LIBF) is a multisystem disorder characterized by early-onset retinal degeneration, sensorineural hearing loss, microcephaly, intellectual disability, and skeletal dysplasia with scoliosis and short stature. It has been reported that mutations in PISD cause this syndrome. The phosphatidylserine decarboxylase (PISD) is located in the inner mitochondrial membrane, and is responsible for the conversion of phosphatidylserine (PS) to phosphatidylethanolamine (PE), a process that is essential in all living organisms.
