Abstract
- Purpose: To identify the causative variants in two unrelated Chinese patients presenting with epilepsy and deafness. Methods: The two patients underwent a thorough examination, including brain MRI, EEG and metabolic studies. Next‐generation sequencing (NGS) was performed on genomic DNA samples from the siblings and parents. Sanger sequencing was used to confirm the variants. Results: Gene sequencing revealed that they carried two novel compound heterozygous missense variants of the TBC1D24: c.116 C > T (p.Ala39Val) and c.827 T > C (p.Ile276Thr) in patient 1; c.404 C > T (p.Pro135Leu) and c.679 T > C (p.Arg227Trp) in patient 2. Audiologic examination showed bilateral sensorineural hearing loss in both patients. Conclusion: We have found novel variants in the TBC1D24 in two Chinese unrelated patients. They result in a rare phenotype, characterized by drug‐resistant epilepsy and deafness. [ABSTRACT FROM AUTHOR]
