N1 - Funding Information:
We are grateful to the families who voluntarily participated in this study in Puerto Rico, Ethiopia, Nigeria, Ghana, Iowa, and the Philippines. We are also grateful to all the administrative and research staff, students, nurses and resident doctors who assisted with participant recruitment, consent, and data collection. We appreciate the contribution of our late colleague, Muhammad Musa who designed and sequenced the ACVR1 gene in multiple populations. This research is supported by the National Institute of Dental and Craniofacial Research (R00 DE022378 and R01DE028300; A.B., R00 DE024571; C.B., R03 DE024776; S.A.L.) and the National Institute on Minority Health and Health Disparities (S21 MD001830; C.B., U54 MD007587; C.B.).

N2 - Objectives: Cleft lip with/without cleft palate and cleft palate only are congenital birth defects where the upper lip and/or palate fail to fuse properly during embryonic facial development. Affecting ~1.2/1000 live births world-wide, these orofacial clefts impose significant social and financial burdens on affected individuals and their families. Orofacial clefts have a complex etiology resulting from genetic variants combined with environmental covariates. Recent genome-wide association studies and whole-exome sequencing for orofacial clefts identified significant genetic associations and variants in several genes. Of these, we investigated the role of common/rare variants in SHH, RORA, MRPL53, ACVR1, and GDF11.Materials and methods: We sequenced these five genes in 1255 multi-ethnic cleft lip with/without palate and cleft palate only samples in order to find variants that may provide potential explanations for the missing heritability of orofacial clefts. Rare and novel variants were further analyzed using in-silico predictive tools.Results: 19 total variants of interest were found, with variant types including stop-gain, missense, synonymous, intronic, and splice-site variants. Of these, 3 novel missense variants were found, one in SHH, one in RORA, and one in GDF11.Conclusion: This study provides evidence that variants in SHH, RORA, MRPL53, ACVR1, and GDF11 may contribute to risk of orofacial clefts in various populations.
