What is the CLN1 gene?

CLN1 disease is an inherited disorder that primarily affects the nervous system. Individuals with this condition have normal development in infancy, but typically by 18 months they become increasingly irritable and begin to lose previously acquired skills (developmental regression).

What is CLN2 disease?

Description. Collapse Section. CLN2 disease is an inherited disorder that primarily affects the nervous system. The signs and symptoms of this condition typically begin between ages 2 and 4. The initial features usually include recurrent seizures (epilepsy) and difficulty coordinating movements (ataxia).

Is Batten’s disease hereditary?

Batten disease is an inherited genetic disorder that appears to affect the function of tiny bodies within cells called lysosomes.

What does CLN3 stand for?

CLN3 (CLN3 Lysosomal/Endosomal Transmembrane Protein, Battenin) is a Protein Coding gene. Diseases associated with CLN3 include Ceroid Lipofuscinosis, Neuronal, 3 and Neuronal Ceroid Lipofuscinosis.

What is INAD life expectancy?

For the first few years, a baby with INAD will be alert and responsive, despite being increasingly physically impaired. Eventually, because of deterioration in vision, speech, and mental skills, the child will lose touch with its surroundings. Death usually occurs between the ages of 5 to 10 years.

What is infantile Batten disease?

Infantile Batten is a subtype of Batten disease, a progressive and inherited disorder of the nervous system that’s also known as neuronal ceroid lipofuscinoses (NCL). Batten disease has several types, generally classified by the gene involved and the age at which symptoms start.

How common is CLN2?

Has an estimated incidence of ~0.5 per 100,000 live births. Most commonly presents as the late–infantile phenotype. Mutations in the CLN2/TPP1 gene, which is located on chromosome 11p15 [63], result in deficient lysosomal activity of tripeptidyl-peptidase 1 (TPP1)

Can children with INAD hear?

Children with INAD may also experience: Ataxia (coordination and balance problems). Difficulty swallowing (dysphagia). Hearing loss.

Can you recover from INAD?

INAD has no cure, and no treatment will reverse or stop the progression of symptoms. Instead, treatments aim to prevent complications, ease symptoms, and improve the child’s quality of life. A typical treatment plan may include: Medications to control muscle stiffness.

Are people born with Batten disease?

Batten disease is a genetic disorder. It’s inherited (passed down through families). It only happens when both parents are carriers of a gene with a mutation (mistake). For a baby to be born with Batten disease, both parents must pass along a copy of the faulty gene.

What is batten’s disease life expectancy?

Children with Batten disease have a greatly shortened life expectancy. Children with infantile Batten disease often die in early childhood. Children with later onset forms of the disease may live into their teens to thirties, while those who develop the disease in adulthood may have a normal life expectancy.

Are you born with INAD?

Infantile: INAD is present at birth (a congenital disease). Symptoms typically appear during infancy and before a child is 3 years old. Neuroaxonal: The disease affects axons in nerve cells. Axons carry messages from your brain to the rest of your body.

Can INAD be detected before birth?

Is prenatal testing available? Due to recent advances in genetic studies, prenatal testing for INAD is now usually possible if the PLA2G6 gene has been found in the affected child.

Can kids with INAD see?

Is INAD curable?

INAD is genetic, so NYSCF is working on gene editing patient cells to yield insights into what drives the disease and accelerate treatment development. Gene editing may even hold promise for a cure — by directly fixing the disease-causing mutation to knock out the disease once and for all.
