Abstract

Background: Ciliopathies are characterized by the dysfunction of cilia, being inherited retinal dystrophies (IRDs) included in sensory ciliopathies. Besides, oro-facial-digital syndrome (OFD) is caused by mutations in ciliary genes, leading to dysmorphic features. Mutations in TBC1D32 were associated to retinal dystrophy and OFD, defining this form as OFD-IX.

Results: A clinical exome analysis performed on a patient presenting with OFD-IX and sensorineural hearing loss (SNHL) identified two variants in TBC1D32, one of which affects splicing, with its impact validated using a minigene assay.

Conclusions: These results suggest that SNHL may represent a new clinical feature associated with this gene.

TBC1D32基因的两个新突变增加了颅面指综合征的复杂性。

背景：纤毛病以纤毛功能障碍为特征，包括遗传性视网膜营养不良（IRDs）在内的感觉纤毛病。此外，oro- face -digital syndrome （OFD）是由纤毛基因突变引起的畸形特征。TBC1D32突变与视网膜营养不良和OFD有关，将这种形式定义为OFD- ix。结果：对一名患有OFD-IX和感音神经性听力损失（SNHL）的患者进行的临床外显子组分析发现了TBC1D32的两种变体，其中一种影响剪接，其影响使用minigene assay验证。结论：这些结果提示SNHL可能代表了与该基因相关的一种新的临床特征。
