Neuronal Ceroid Lipofuscinosis 4B



  • This text brings together leading authorities presenting state-of-the-art clinical reviews covering the science, recognition, and treatment of the inherited metabolic epilepsies and related disorders.[books.google.com]
  • Clinical description The clinical presentation varies widely between forms but the clinical hallmark is a combination of dementia, visual loss, and epilepsy.[orpha.net]
  • CLN2 disease most commonly presents with seizures and/or ataxia in the late-infantile period (ages 2–4), often in combination with a history of language delay, followed by progressive childhood dementia, motor and visual deterioration, and early death[moh-it.pure.elsevier.com]
  • Results: The present patient was a 4-year-old girl who presented at 2 years and 10 months old with seizures followed by ataxia, regression of skills, and eventual visual decline. TPP1 enzyme activity was below normal for age.[atm.amegroups.com]

Mental Deterioration
  • The early symptoms are followed by epilepsy and progressive physical and mental deterioration. Batten disease gene maps to chromosome 16p12.1. 56 chromosome haplotype defined by alleles at the d16s299 is shared by 73% of batten disease chromosomes.[icd10data.com]

  • Management and treatment There is no curative treatment for NCLs and management is supportive only.[orpha.net]


  • Prognosis Although all NCLs lead to severe disability, the prognosis is variable with life expectancy ranging from a few hours or days after birth for the congenital form to survival into the fifth decade for patients with the adult-onset form.[orpha.net]
  • Prognosis There will be mental impairment, worsening seizures and progressive loss of sight and motor skills. Batten's syndrome is often fatal by the late teens or twenties.[patient.info]
  • HER2 expression in breast cancer is associated with poor prognosis ( 26 ).[frontiersin.org]


  • Etiology To date, at least 10 genetic NCL disorders have been reported and are designated as CLN1 to CLN10.[orpha.net]
  • To date no specific enzymatic deficiency as the etiology of the condition is known.[healio.com]
