  • 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]
  • 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]
  • The present diagnosis of Leber’s congenital amaurosis is not a clinical syndrome but an aspecific symptom complex. 1979 S. Karger AG, Basel Article / Publication Details First-Page Preview[karger.com]
  • 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]

  • Management and treatment There is no curative treatment for NCLs and management is supportive only.[orpha.net]
  • Management and treatment Treatment is supportive only and should consist of palliative care with administration of anticonvulsive drugs; as well as educational, psychological, and psychiatric management.[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 The prognosis for JNCL is severe but life expectancy varies with some patients surviving to the fourth decade. The documents contained in this web site are presented for information purposes only.[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]


  • The syndromic approach is completed by an etiological approach, based on the major advances in genetics and functional genetics.[books.google.com]
  • Etiology To date, at least 10 genetic NCL disorders have been reported and are designated as CLN1 to CLN10.[orpha.net]
  • Etiology JNCLs are transmitted in an autosomal recessive manner and mutations in the following genes may result in JNCL with a classic and/or variant phenotype: PPT1 (designated CLN1 ; 1p32), TPP1 (11p15; designated CLN2 ), CLN3 (16p12), CLN8 (8p23; responsible[orpha.net]
  • To date no specific enzymatic deficiency as the etiology of the condition is known.[healio.com]


  • It was necessary to justify the physiological, epidemiologic, genetic and therapeutic approaches and to consider them in the light of the new classification efforts, which are still in the making.[books.google.com]
  • Summary Epidemiology The exact prevalence and incidence of this group of disorders are unknown.[orpha.net]
  • Summary Epidemiology Worldwide prevalence is unknown.[orpha.net]
  • Epidemiology It is a rare condition with a variable incidence across different countries.[patient.info]
