A Brazilian family with Brown-Vialetto-van Laere syndrome with autosomal recessive inheritance.

چکیده
We report the first Brazilian family with Brown-Vialetto-van Laere syndrome. The presence of consanguineous marriages and illness affecting three sisters and one niece support an autosomal recessive transmission. The age at onset of the illness ranged from 12 to 20 years old. The time interval between hearing loss and involvement of other cranial nerves varied from 3 to 12 years. MRI demonstrated bulbar atrophy and also high intensity signal at T2 weighted and fluid attenuated inversion recovery (FLAIR) sequences.

Pontobulbar palsy and neurosensory deafness (Brown-Vialetto-Van Laere syndrome) with possible autosomal dominant inheritance.
A female with the Brown-Vialetto-Van Laere syndrome is described. The patient's father, a paternal uncle, and possibly a paternal first cousin had neurosensory deafness and a paternal aunt had clinical symptoms indicative of the syndrome. This family raises the possibility that the disorder is genetically heterogeneous with autosomal recessive and autosomal dominant forms. Alternatively, it cou...

Riboflavin transporter deficiency (formerly known as Brown-Vialetto-Van Laere [BVVL] or Fazio-Londe syndrome) is a neurodegenerative disorder characterized by progressive bulbar palsy with sensorineural deafness or bulbar hereditary neuropathy. It is caused by mutations in the riboflavin transporter genes SLC52A2 (RFVT2) or SLC52A3 (RFVT3). It is a rare syndrome with approximately 70 cases repo...

متن کاملA Case of Brown-Vialetto-Van Laere Syndrome Due To a Novel Mutation in SLC52A3 Gene
Brown-Vialetto-Van Laere syndrome is a rare disorder characterized by motor, sensory, and cranial neuronopathies, associated with mutations in SLC52A2 and SLC52A3 genes that code for human riboflavin transporters RFVT2 and RFVT3, respectively. The authors describe the clinical course of a 6-year-old girl with Brown-Vialetto-Van Laere syndrome and a novel homozygous mutation c.1156T>C in the SLC...
