Batten
disease:
Neuronal Ceroid Lipofuscinosis Type 1 (infantile);
Type 2 (late infantile); Type 3 (Juvenile);
NCL; Santavuori disease; Santavuori-Haltia disease (Infantile);
Jansky-Bielschowsky disease (Late Infantile Type);
Variant late infantile type; Vogt-Spielmeyer
disease (Juvenile type); Kufs disease (Adult
type)
The group of
diseases known as Batten disease (after the British Paediatrician
who first described it in 1903) or the neuronal ceroid
lipofuscinoses (NCLs) are rare, genetic, progressive
neurodegenerative, metabolic diseases that occur in children and
adults worldwide.
Symptoms
include loss of vision, epilepsy and loss of abilities including
walking, eating and talking. Our understanding of Batten disease is
improving all the time and work to develop new therapies is
progressing well. However, at present there is no cure or treatment
that makes a significant impact on the progressive decline in bodily
functions and inevitable early death.
A number of
different forms of Batten disease, including less common variants
and a congenital form are known. These share similar symptoms but
progress at different rates and are all genetically different. It
is important to know which gene mutation causes the disease in each
individual. Nine genes are known to cause Batten disease to date.
The types of Batten disease are often classified by age of onset:
Infantile
– onset between
6 months and 2 years. Death can occur in mid-childhood.
Late
Infantile
and variant late infantile – onset between 2 and 4 years. Death can
occur between the ages of 5 and 15.
Juvenile
– onset between 5 and 9 years. Death can occur from the late
teens to the mid 30's.
Adult
– onset normally before the age of 40. Shortened life expectancy.
Inheritance patterns
Autosomal recessive for all the childhood variants of NCL (neuronal
ceroid lipofuscinoses), however it is thought that some of the rare
adult forms (Kuf's disease) can be inherited in an autosomal
dominant way.
Prenatal diagnosis
Prenatal diagnosis is available in the UK within the National Health
Service for families in which the histology and genetics are known
for an affected child. At present this covers types caused by
mutations in the genes CLN1, CLN2, CLN3, CLN5, CLN6, CLN7, CLN8,
CLN10. Prenatal diagnosis is done using a chorionic villus sample
which is split and sent for ultrastructural analysis, DNA mutation
testing (all types) and enzyme analysis (CLN1, CLN2, CLN10/CTSD).
