Project description:A 640kb non-coding interval at 8q24 has been associated with an increased risk of non-syndromic cleft lip and palate (CLP) in humans, but the genes and pathways involved in this genetic susceptibility have remained elusive. With a large series of rearrangements engineered over the syntenic mouse region, we showed that this interval contains very remote cis-acting enhancers that control c-myc expression in the developing face. Deletion of this interval led to mild alteration of facial morphologies in mice and, sporadically, to CLP. At a molecular level, we identified mis-expression of several downstream genes, highlighting a combined impact on cranio-facial developmental network and general metabolic capacity. This dual molecular etiology may account for the prominent role to the 8q24 region in human facial dysmorphologies. ChIP-seq and transcriptomics analysis in wt or/and mutant mice

Project description:Cleft lip with or without cleft palate (CL/P) is a common birth defect with a complex, heterogeneous etiology. It is well-established that both common and rare sequence variants contribute to the formation of CL/P, however, the contribution of copy number variants (CNVs) to cleft formation remains relatively understudied. To fill this knowledge gap, we conducted a large-scale comparative analysis of genome-wide CNV profiles of 869 individuals from the Philippines and 233 individuals of European ancestry with CL/P with three primary goals: first, to evaluate whether differences in CNV number, amount of genomic content, or amount of coding genomic content existed within clefting subtypes; second, to assess whether CNVs in our cohort overlapped with known Mendelian clefting loci; and third, to identify unestablished Mendelian clefting genes. Significant differences in CNVs across cleft types or in individuals with non-syndromic versus syndromic clefts were not observed, however, several CNVs in our cohort overlapped with known syndromic and non-syndromic Mendelian clefting loci. Moreover, employing a filtering strategy relying on population genetics data that rare variants are on the whole more deleterious than common variants, we identify several CNV-associated gene losses likely driving non-syndromic clefting phenotypes. By prioritizing genes deleted at a rare frequency across multiple individuals with clefts yet enriched in our case cohort compared to controls, we identify COBLL1, RIC1, and ARHGEF38 as clefting genes. CRISPR/Cas9 mutagenesis of these genes in Xenopus laevis and Danio rerio yielded craniofacial dysmorphologies, including clefts analogous to those seen in human clefting disorders.

Project description:The transcription factor Interferon Regulatory Factor 6 (IRF6) is crucially involved in craniofacial development and regulates the proliferation/differentiation balance in keratinocytes. Pathological IRF6 variants have been found in Van der Woude syndrome (VWS), the most common syndromic form of cleft lip / palate (CLP) as well as in non-syndromic CLP cases. Besides its prominent function in regulating keratinocyte differentiation, recent data revealed that IRF6 is also involved in wound healing and migration. Since a significant fraction of CLP patients undergoing corrective cleft surgery experience wound healing complications, IRF6 represents an interesting candidate gene linking the two processes. However, Irf6 function has been mainly studied in mice and knowledge on IRF6 in human cells remains sparse. Here, we aimed to elucidate the role of IRF6 in human postnatal skin- and oral mucosa-derived keratinocytes by its ablation using CRISPR/Cas9. We complement this approach by applying proteomics and identify that lack of IRF6 disrupts human epithelial homeostasis by altering cell colony morphology, migration pattern, and the differentiation potential of keratinocytes.
