Summary
Identifying genes for cleft lip/palate (CL/P) and cleft palate (CP) aids understanding of oral development and recurrence risk. Further research is needed to confirm these crucial orofacial cleft genes.
Area of Science:
- Genetics
- Developmental Biology
- Craniofacial Anomalies
Background:
- Nonsyndromic cleft lip with or without a cleft palate (CL/P) and cleft palate alone (CP) are common congenital anomalies.
- Understanding the genetic basis of CL/P and CP is crucial for molecular developmental insights and recurrence risk prediction.
Purpose of the Study:
- To review the current knowledge on the search for genes associated with CL/P and CP.
- To highlight the ongoing efforts and future directions in identifying orofacial cleft genes (OFC).
Main Methods:
- Literature review of genetic association studies for CL/P and CP.
- Analysis of candidate genes and chromosomal regions implicated in orofacial clefts.
Main Results:
- Approximately twenty candidate genes have been proposed for CL/P and CP after a decade of research.
- Certain genes and chromosomal regions show frequent associations with these conditions.
- A specific nomenclature, orofacial cleft genes (OFC), has been suggested.
Conclusions:
- Confirmation of genes responsible for CL/P and CP requires extensive further research.
- Identifying these genes will significantly improve the prediction of recurrence risks for affected families.
- Continued research into OFC genes is essential for advancing the understanding and management of orofacial clefts.
