• Difficulty Walking

  People with this form of CLN8 disease have increasing difficulty walking and coordinating movements (ataxia), eventually becoming immobile. [icdlist.com]

• Leg Weakness

  Eventually, usually during the late teens or twenties, additional abnormalities develop including sudden involuntary muscle contractions (myoclonus), muscle spasms (spasticity) that result in slow, stiff movements of the legs, weakness or paralysis of [rarediseases.org]

• Myoclonus

  Other features like myoclonus, ataxia and vision loss develop later in the course with optic atrophy being detectable within 2½ years of vision loss. [annalsofian.org]

  As with younger affected children, older individuals develop a decline in intellectual function, myoclonus, epilepsy, and vision loss. [icdlist.com]

  Clinical manifestations include seizures, progressive mental and motor deterioration, myoclonus, visual failure, dementia and premature death. [alliedacademies.org]

  Involuntary movements (ataxia, myoclonus or spastic quadriparesis) occur. Myoclonus may be severe and refractory to medications. Visual loss occurs but is less obvious for the same reason as in CLN1. ERG is effective to evaluate visual acuity. [omicsonline.org]

Although there currently is no treatment for this condition, making the correct diagnosis is important for appropriate low-vision management, educational planning, and genetic counseling. [ncbi.nlm.nih.gov]

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 Affected children suffer increasing mental impairment, worsening seizures, and progressive loss of sight and motor skills. Eventually, children with Batten disease become blind, bedridden and demented. [brainfoundation.org.au]

Early recognition of cardiac involvement may have led to early intervention with medication but it is difficult to speculate if this would have impacted on his overall morbidity or prognosis. [academic.oup.com]

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]
