Fifteen years of research on oral-facial-digital syndromes: from 1 to 16 causal genes
2017
Oral–facial–digital syndromes (OFDS) gather rare genetic disorders characterised by facial, oral and digital abnormalities associated with a wide range of additional features (polycystic kidney disease, cerebral malformations and several others) to delineate a growing list of OFDS subtypes. The most frequent, OFD type I, is caused by a heterozygous mutation in theOFD1gene encoding a centrosomal protein. The wide clinical heterogeneity of OFDS suggests the involvement of other ciliary genes. For 15 years, we have aimed to identify the molecular bases of OFDS. This effort has been greatly helped by the recent development of whole-exome sequencing (WES). Here, we present all our published and …
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…
