Battens disease

Commonly referred to as Batten disease, the Neuronal Ceroid Lipofuscinoses NCLs denote several different genetic life-limiting neurodegenerative diseases that share similar features. Since then over mutations in 13 different genes have been described that cause the various forms of NCL disease.

Our cells contain thousands of genes that are lined up along chromosomes. Human cells contain 23 pairs of chromosomes 46 in total.

What is Batten disease?

Most genes control the manufacture of at least one protein. These proteins have different functions and include enzymes which act to speed up molecular chemical reactions. The NCLs are caused by abnormal genes, which are unable to produce the required proteins.

As a result, the cells do not work properly and this leads to the development of symptoms associated with these diseases. How are NCLs inherited? This is one of several ways that a trait, disorder, or disease can be passed down through families.

An autosomal recessive disorder means that both copies of the gene are abnormal one from each parent with neither working properly. Therefore the disease does not depend on the sex of an individual and both biological parents, of a child with this diagnosis, will be carriers of the disease but physically unaffected by it.

What are the chances of inheriting an NCL?

When it is known that both parents are carriers of the abnormal gene, we refer to there being a 2 in 3 chance of a child being a carrier, once it is established that they are unaffected by the disease. How common is it? We estimate that approximately 1 — 3 children are diagnosed with an infantile form of the disease each year, meaning there are probably between 15 and 30 affected children in the UK.

We estimate that approximately 7 — 10 children are diagnosed with a late-infantile including variants form of the disease each year, meaning there are probably between 30 and 60 affected children and young people in the UK. We estimate that approximately 3 — 4 children are diagnosed with a juvenile form of the disease each year, meaning there are probably between 30 — 40 affected children and young people in the UK.

Adult NCL see below is extremely rare, although affected families have been identified in several different countries. Subsequently, we estimate that there are approximately — children, young people and adults currently living with an NCL diagnosis in the UK.

What are the symptoms and how does the disease progress? These include an increasing visual impairment resulting in blindness; complex epilepsy with severe seizures that are difficult to control; myoclonic rapid involuntary muscle spasm jerks of limbs; difficulties sleeping; the decline of speech, language and swallowing skills; and a deterioration of fine and gross motor skills that result in the loss of mobility.

Ultimately the child or young person will become totally dependent on families and carers for all of their needs. Other symptoms that are commonly seen are hallucinations, memory loss and challenging behaviours.Batten disease is a rare, fatal, inherited disorder of the nervous system that typically begins in childhood.

The first symptom is usually progressive vision loss in previously healthy children followed by personality changes, behavioral problems and slow learning. Batten disease (Neuronal Ceroid Lipofuscinoses) is an inherited disorder of the nervous system that usually manifests itself in childhood.

Batten disease is named after the British paediatrician who first described it in Batten Disease News is strictly a news and information website about the disease.

Batten disease, or Neuronal Ceroid Lipofuscinosis (NCL), is a family of rare diseases caused by autosomal recessive genetic mutations resulting in the body. These genetic mutations disrupt the cells' ability to dispose of wastes.
