New Insights into the Neurodegeneration Mechanisms Underlying Riboflavin Transporter Deficiency (RTD): Involvement of Energy Dysmetabolism and Cytoskeletal Derangement [PDF]
Riboflavin transporter deficiency (RTD) is a rare genetic disorder characterized by motor, sensory and cranial neuropathy. This childhood-onset neurodegenerative disease is caused by biallelic pathogenic variants in either SLC52A2 or SLC52A3 genes ...

Riboflavin Transporter Deficiency Type 2: Expanding the Phenotype of the Lebanese Founder Mutation p.Gly306Arg in the SLC52A2 Gene [PDF]
Background: Riboflavin transporter deficiency type 2 is an ultra-rare, yet treatable, inborn error of metabolism. This autosomal recessive disorder is caused by pathogenic mutations in the SLC52A2 gene leading to progressive ataxia, polyneuropathy, and ...

Mitochondrial and Peroxisomal Alterations Contribute to Energy Dysmetabolism in Riboflavin Transporter Deficiency. [PDF]
Riboflavin transporter deficiency (RTD) is a childhood-onset neurodegenerative disorder characterized by progressive pontobulbar palsy, sensory and motor neuron degeneration, sensorineural hearing loss, and optic atrophy. As riboflavin (RF) is the precursor of FAD and FMN, we hypothesize that both mitochondrial and peroxisomal energy metabolism ...

Benefit of high‐dose oral riboflavin therapy in riboflavin transporter deficiency
AbstractRiboflavin transporter deficiency (RTD) is a progressive inherited neuropathy of childhood onset, characterised by pontobulbar palsy, sensorineural deafness, sensory ataxia, muscle weakness, optic atrophy and respiratory failure. Riboflavin supplementation is beneficial in short‐term reports, but the quantum of benefit in various clinical ...

Summary: Ablation of Slc22a14 causes male infertility in mice, but the underlying mechanisms remain unknown. Here, we show that SLC22A14 is a riboflavin transporter localized at the inner mitochondrial membrane of the spermatozoa mid-piece and show by ...

Long-term outcomes in children with riboflavin transporter deficiency and surveillance recommendations. [PDF]
AbstractThe aim of this longitudinal case series was to describe long‐term functional outcome in a group of individuals with riboflavin transporter deficiency (RTD) treated with high‐dose oral riboflavin. Data were collected between 2012 to 2022. Eleven individuals with RTD were assessed at 12‐month intervals for monitoring of disease progression ...

Role of Otolaryngologists in the Treatment of Patients With Riboflavin Transporter Deficiency: A Case Report. [PDF]
Riboflavin transporter deficiency (RTD) is a rare genetic disorder that can have detrimental effects on the nervous system, causing progressive neurodegeneration. Here, we report the second case of RTD in Saudi Arabia. An 18-month-old boy presented to the otolaryngology clinic with six weeks history of progressive noisy breathing associated with ...

Successful treatment of a genetic childhood ataxia due to riboflavin transporter deficiency. [PDF]
Riboflavin transporter deficiency (Brown-Vialetto-Van Laere syndrome) is a rare recessive neurodegenerative disorder that can present with gait ataxia, primarily due to sensory neuropathy as well as cerebellar involvement. Although sensorineural hearing loss, bulbar palsy, and optic atrophy are typical, presentation may be variable and an atypical ...
