                Orofacial clefting (OFC) is a frequent congenital anomaly and can occur either in the context of underlying syndromes or in isolation (nonsyndromic). The two common OFC phenotypes are cleft lip with/without cleft palate (CL/P) and cleft palate only (CPO). In this study, we searched for penetrant CL/P genes, by evaluating de novo copy number variants (CNV) from an exome sequencing dataset of 50 nonsyndromic patient-parent trios. We detected a heterozygous 86 kb de novo deletion affecting exons 4-11 of ZFHX4, a gene previously associated with OFC. Genetic and phenotypic data from our in-house and the AGORA cohort (710 and 229 individuals with nonsyndromic CL/P) together with literature and database reviews demonstrate that ZFHX4 variants can lead to both nonsyndromic and syndromic forms not only of CL/P but also CPO. Expression analysis in published single-cell RNA-sequencing data (mouse embryo, zebrafish larva) at relevant time-points support an important role of Zfhx4/zfhx4 in craniofacial development. To characterize the role of zfhx4 in zebrafish craniofacial development, we knocked out/down the zebrafish orthologue. Cartilage staining of the zfhx4 CRISPR F0 knockout and morpholino knockdown at 4 days post-fertilization showed an underdeveloped and abnormally shaped ethmoid plate and cartilaginous jaw (resembling micrognathia). While there is evidence for the dominant inheritance of ZFHX4 variants in OFC, we here present a patient with a possible recessive inheritance. In conclusion, ZFHX4 has a highly heterogeneous phenotypic spectrum and variable mode of inheritance. Our data highlight that ZFHX4 should be considered in genetic testing in patients with nonsyndromic clefting.
