Presentation
Common presentations involve bulbar palsy (92%), hearing loss (81%), facial weakness (77%), respiratory compromise (64%), and muscle weakness (55%). 3 The mean age of onset is 8.2 years. 2 Our case presented all these common phenotypes starting at the [nature.com]
Abstract We report on three patients (two siblings and one unrelated) presenting in infancy with progressive muscle weakness and paralysis of the diaphragm. [doi.org]
FL is said to present in the first decade of life while BVVL presented in the 2 nd decade of life. [ncbi.nlm.nih.gov]

Two children presented in the first 16 months of life with stridor and died of respiratory failure by the age of 2 years. Hearing loss was not apparent in these infants. [ncbi.nlm.nih.gov]
This condition is characterized by facial weakness, dysphagia, stridor, dysarthria, and paralysis of the eye muscles. [diseaseinfosearch.org]
Symptoms of Fazio-Londe disease appear between 1 and 12 years of age and may include facial weakness, dysphagia (difficulty swallowing), stridor (a high-pitched respiratory sound often associated with acute blockage of the larynx), difficulty speaking [motor-neuron.com]

Ears
- Hearing Impairment
The other four cases reported in our country were female, all sporadic with negative family history and presented with bilateral hearing loss. [4] However, in few studies other findings were preceding the hearing impairment, as Sathasivam et al. reported [pediatricneurosciences.com]
No hearing impairment is seen. Spinal muscular atrophy The clinical picture of spinal muscular atrophy (SMA) is highly variable and represents a continuum. The age of onset ranges from before birth to adulthood. [emedicine.medscape.com]

- Hyperreflexia
Clinical manifestations include progressive weakness, atrophy, fasciculation, hyperreflexia, dysarthria, dysphagia, and eventual paralysis of respiratory function. [icd9data.com]
The essential clinical findings are slowly progressive and often include severe spasticity, hyperreflexia, and weakness in a pyramidal distribution, noticeably in both lower limbs, with extensor plantar responses. [emedicine.medscape.com]
- Areflexia
In this slowly progressive condition, hearing loss and vestibular areflexia are almost always the first symptoms, occurring in late childhood or early adulthood. [jamanetwork.com]

The infant fully recovered after riboflavin treatment[ 10, 11 ]. [doi.org]
Treatment Currently, no cure or standard treatments have been found for the disease. However, its early detection provides an optimal situation wherein doctors can devise a treatment plan for the condition. [medigest.uk]
However, because the disease is so often fatal without treatment, and because the treatment is so inexpensive and with little risk, it is recommended that if the disease is suspected that riboflavin therapy be started immediately while testing is in progress [en.wikipedia.org]

Pathophysiology
However, since 2010 insights into the pathophysiology, genetics and treatment of this disorder have increased tremendously. [doi.org]
Pathophysiology The disease causes fatty liver with minimal inflammation, and severe encephalopathy (with swelling of the brain). The liver may become slightly enlarged and firm, and there is a change in the appearance of the kidneys. [wikidoc.org]
Milder phenotypes do occur, but rarely present past the third decade. 1, 2 Despite its first description in 1894, only recently has an understanding of the genetic and pathophysiological basis for BVVL opened the opportunity for therapeutic intervention [pn.bmj.com]
