The parents of an affected individual are obligate heterozygotes and are therefore asymptomatic carriers. Genetic counseling should be provided to affected families.[orpha.net]
Heterozygotes (carriers) are asymptomatic. Sibs of a proband At conception, each sib of an affected individual has a 25% chance of being affected, a 50% chance of being an asymptomatic carrier, and a 25% chance of being unaffected and not a carrier.[cmm.ucsd.edu]

Prognosis - Juvenile primary lateral sclerosis he \'prognosis\' of Juvenile primary lateral sclerosis usually refers to the likely outcome of Juvenile primary lateral sclerosis.[checkorphan.org]
Prognosis A distinctive clinical feature of PLS is that it has a very slow progression, leading it to be considered to have a more benign prognosis in comparison to ALS [3] .[physio-pedia.com]

OBJECTIVE: To determine the genetic etiology in 2 consanguineous families who presented a novel phenotype of autosomal recessive juvenile amyotrophic lateral sclerosis associated with generalized dystonia.[foundationdystoniaresearch.org]
Etiology and Patogenesis There is one special form of PLS, which occurs in childhood, called juvenile primary lateral sclerosis. Nowadays, we know that there is a gene transmited from parents to their children, called ALS2.[wikilectures.eu]
The etiology of amyotrophic lateral sclerosis is likely to be multifactorial, involving both genetic and environmental factors. The disease is inherited in 5-10% of the cases. {ECO:0000269 PubMed:11586298}.[genecards.org]

Epidemiology Found in 1–3% of patients with motor neuron disorder Onset is usually after age 40 years, although a juvenile form has been described. Mean age at symptom onset is 54 years. There is a slight male predominance, which is similar to ALS.[unboundmedicine.com]
Clinically Relevant Anatomy Epidemiology [3] Approximately 2-5% of adults in neuromuscular clinics are diagnosed with PLS. The age of onset is approximately 50 years and older, though a juvenile-onset form of PLS has been identified as well.[physio-pedia.com]
Progress has been made in understanding the genetic defects and the pathophysiology of this crippling motor neuron disease (commonly called Lou Gehrig’s disease).[nejm.org]
Etiology and Pathophysiology PLS is usually sporadic with no known cause; potential role of TAR DNA–binding protein 43 (TDP-43) ( 1 ) Genetics Juvenile PLS and juvenile ALS has been correlated with a mutation in the ALS2 gene on chromosome 2.[unboundmedicine.com]
