General Discussion

Batten disease, a rare genetic disorder, belongs to a group of progressive degenerative neurometabolic disorders known as the neuronal ceroid lipofuscinoses. These disorders share certain similar symptoms and are distinguished in part by the age at which such symptoms appear. Batten disease is sometimes considered the juvenile form of the neuronal ceroid lipofuscinoses (NCLs). The NCLs are characterized by abnormal accumulation of certain fatty, granular substances (i.e., pigmented lipids [lipopigments] ceroid and lipofuscin) within nerve cells (neurons) of the brain as well as other tissues of the body that may result in progressive deterioration (atrophy) of certain areas of the brain, neurological impairment, and other characteristic symptoms and physical findings.



The symptoms of Batten disease usually become apparent between 5 and 15 years of age when progressive loss of vision, seizures, and progressive neurological degeneration develop. In some cases, initial symptoms may be more vague and include clumsiness, balance problems and behavioral or personality changes. Batten disease is inherited as an autosomal recessive trait and occurs most in families of Northern European or Scandinavian ancestry and is found worldwide.



For years, the term Batten disease was used to describe the chronic juvenile form of NCL (JNCL). Recently, some researchers have begun using the term Batten disease to encompass all types of neuronal ceroid lipofuscinoses.

Symptoms

The symptoms of Batten disease usually become apparent between 5 and 15 years of age. Affected children may develop slowly progressive vision abnormalities, cognitive decline, and behavioral changes.



An early finding in Batten disease is the progressive loss of vision characterized macular degeneration, deterioration of the nerves of the eyes (optic nerves) that transmit impulses from the nerve-rich membrane lining the eyes (retina) to the brain (optic atrophy), and abnormal accumulation of colored (pigmented) material on the retinas (retinitis pigmentosa). Retinitis pigmentosa eventually causes degeneration of the retina leading to progressive loss of vision. Children with Batten disease often lose their sight by the age of 10.



In some children, the first signs of Batten disease are episodes of uncontrolled electrical disturbances in the brain (seizures) and the loss of previously acquired physical and mental abilities (developmental regression). As affected individuals age, seizures worsen, signs of dementia become apparent, and motor abnormalities similar to those seen in Parkinson's disease develop. During this period, behavioral and personality changes often occur including mood disturbances, anxiety, psychotic states (such as explosive, unprovoked laughing and/or crying), and hallucinations. Speech disturbances such as stuttering may also occur.



Eventually, usually during the late teens or twenties additional abnormalities develop including sudden involuntary muscle contractions (myoclonus), muscle spasms (spasticity) that result in slow, stiff movements of the legs, weakness or paralysis of all four limbs (quadriparesis), and sleep disturbances. In most cases, progressive neurological and mental degeneration leaves affected individuals bedridden and unable to communicate easily and eventually results in life-threatening complications by the twenties.

Causes

Batten disease is inherited as an autosomal recessive trait. Genetic diseases are determined by the combination of genes for a particular trait that are on the chromosomes received from the father and the mother. Recessive genetic disorders occur when an individual inherits the same abnormal gene for the same trait from each parent. If an individual receives one normal gene and one gene for the disease, the person will be a carrier for the disease, but usually will not show symptoms. The risk for two carrier parents to both pass the defective gene and, therefore, have an affected child is 25% with each pregnancy. The risk to have a child who is a carrier like the parents is 50% with each pregnancy. The chance for a child to receive normal genes from both parents and be genetically normal for that particular trait is 25%. The risk is the same for males and females.



Investigators have determined that Batten disease occurs because of disruptions or changes (mutations) of the CLN3 gene located on the short arm (p) of chromosome 16 (16p12.1). The function of the protein encoded by this gene is not yet understood. Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual. Human body cells normally have 46 chromosomes. Pairs of human chromosomes are numbered from 1 through 22 and the sex chromosomes are designated X and Y. Males have one X and one Y chromosome and females have two X chromosomes. Each chromosome has a short arm designated "p" and a long arm designated "q". Chromosomes are further sub-divided into many bands that are numbered. For example, "chromosome 16p12.1" refers to band 12.1 on the short arm of chromosome 16. The numbered bands specify the location of the thousands of genes that are present on each chromosome.



Researchers suspect that Batten disease is caused by alterations within the cell so that the body is unable to break down substances such as fats, and their associated sugars and proteins in the normal way. Some of these fats, sugars, and proteins then appear to form the lipopigments that accumulate in nerve and other tissue causing the symptoms associated with this disorder. Although these substances accumulate in most cells, brain cells are affected first.

Affected Populations

Batten disease affects males and females in equal numbers. In the United States, Batten disease along with the other forms of neuronal ceroid lipofuscinoses, occurs in approximately three in 100,000 births. It can occur with greater frequency in families of Northern European Scandinavian ancestry; in particular, those of Swedish heritage. It is thought to occur in one in 25,000 infants in northern Europe. The symptoms of Batten disease usually begins between five and seven years of age. Batten disease is one of the most common neurodegenerative disorders affecting children.

Standard Therapies

Diagnosis

A diagnosis of Batten disease may be made based upon a thorough clinical evaluation, a detailed patient history, identification of characteristic physical findings, and a variety of specialized tests including the microscopic examination (i.e., electron microscopy) and study of the chemical components (histochemical examination) of samples of tissue (biopsy), usually from the skin. The study of such tissue samples reveals abnormal accumulations of deposits (i.e., pigmented lipids [lipopigments] ceroid and lipofuscin) in membrane-bound cavities within the body (cytoplasm) of cells (inclusion bodies). In JNCL these have a characteristic appearance rather like fingerprints. Similar deposits may also be present in other tissues and cells of the body (e.g., certain white blood cells [lymphocytes].



In addition, in children with Batten disease, electroretinography (ERG), a special instrument that measures the retina's electrical response to light stimulation, may reveal lack of response when the eye is stimulated by light (visually evoked potential [VEP]), confirming progressive retinal pigmentary degeneration and/or optic nerve abnormalities (e.g., optic atrophy). Unique to this type of NCL is the presence of vacuoles in lymphocytes, easily visible at the trailing edges of blood films.



Almost all children affected with JNCL carry a 1kb intragenic deletion that can be detected using a simple DNA-based test.



Treatment

The treatment of Batten disease is directed toward the specific symptoms that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists. Pediatricians, physicians who diagnose and treat neurological disorders (neurologists), eye specialists (ophthalmologists), physical therapists, psychiatrists, and/or other health care professionals may need to systematically and comprehensively plan an affected child's treatment.



Specific therapies for Batten disease are symptomatic and supportive. In some cases, treatment with anticonvulsant drugs such as valproate and lamotrigine may help prevent, reduce, or control various types of seizures associated with Batten disease. Medications may also be used to help psychiatric symptoms such as hallucinations.



Early intervention is important to ensure that children with Batten disease reach their potential. Special services that may be beneficial to affected children may include special remedial education, special social support, and other medical, social, and/or vocational services. Genetic counseling may be of benefit for affected individuals and their families.
