Identification of molecular and physiopathologic basis in oral-facial-digital syndromes

2016

Oral-facial-digital syndromes (OFDS) are characterized by the association of oral, facial and digital anomalies. The different modes of inheritance and additional features lead to clinically delineate 13 subtypes. For a long time, only the OFD1 gene, responsible for OFDI subtype and coding for a centrosomal protein, has been known, suggesting the involvement of the primary cilium in OFDS. Mutations have recently been reported in the TMEM216, DDX59, SCLT1, TBC1D32 and TCTN3 genes in anecdotic cases. To identify new genes involved in OFDS, we performed whole-exome sequencing in 24 patients. In 14/24 cases, we identified 5 novel genes (C2CD3, TMEM107, INTU, KIAA0753, IFT57), enlarged the clini…

Tissue‐dependent differences in Bardet–Biedl syndrome gene expression

2019

BACKGROUND INFORMATION Primary cilia are highly conserved multifunctional cell organelles that extend from the cell membrane. A range of genetic disorders, collectively termed ciliopathies, is attributed to primary cilia dysfunction. The archetypical ciliopathy is the Bardet-Biedl syndrome (BBS), patients of which display virtually all symptoms associated with dysfunctional cilia. The primary cilium acts as a sensory organelle transmitting intra- and extracellular signals thereby transducing various signalling pathways facilitated by the BBS proteins. Growing evidence suggests that cilia proteins also have alternative functions in ciliary independent mechanisms, which might be contributing …

IFT46 Expression in the Nasal Mucosa of Primary Ciliary Dyskinesia Patients: Preliminary Study

2021

Este artículo se encuentra disponible en la siguiente URL: https://journals.sagepub.com/doi/pdf/10.1177/2152656721989288 Background: Primary ciliary dyskinesia (PCD) is characterised by an imbalance in mucociliary clearance leading to chronic respiratory infections. Cilia length is considered to be a contributing factor in cilia movement. Recently, IFT46 protein has been related to cilia length. Therefore, this work aims to study IFT46 expression in a PCD patients cohort and analyse its relationship with cilia length and function, as it was not previously described. Materials and methods: The expression of one intraflagellar transport (IFT46) and two regulating ciliary architecture (FOXJ1 a…
