What is Batten Disease?

Batten disease (also known as Spielmeyer-Vogt-Sjögren-Batten disease) is a rare, fatal autosomal recessive neurodegenerative disorder that begins in childhood. It is the most common form of a group of disorders called neuronal ceroid lipofuscinosis (or NCLs).

Although Batten disease is usually regarded as the juvenile form of NCL (or "type 3"), some physicians use the term Batten disease to describe all forms of NCL. Historically, the NCLs were classified by age of disease onset as infantile NCL (INCL), late infantile NCL (LINCL), juvenile NCL (JNCL) or adult NCL (ANCL).

At least nine genes have been identified in association with Batten disease, but juvenile NCL, the most prevalent form of Batten disease, has been linked to mutations in the CLN3 gene.

Batten disease is named after the British pediatrician Frederick Batten who first described it in 1903. Also known as Spielmeyer-Vogt-Sjögren-Batten disease, it is the most common form of a group of disorders called neuronal ceroid lipofuscinosis (or NCLs). Although Batten disease is usually regarded as the juvenile form of NCL, some physicians use the term Batten disease to describe all forms of NCL.

Batten disease is inherited in an autosomal recessive pattern. The mutation causes the buildup of lipofuscins in the body's tissues. These substances consist of fats and proteins and form certain distinctive deposits that cause the symptoms and can be seen under an electron microscope. The diagnosis of Batten disease is based on the presence of these deposits in skin samples as well as other criteria. Six genes have now been identified that cause different types of Batten disease in children or adults, more having yet to be identified. Two of these genes encode enzymes. The function of most of these genes is still unknown. The identification of these genes opens up the possibility of gene replacement therapy or other gene-related treatments.
