    Abstract:
    OBJECTIVE: To explore the genetic basis for fetuses with cleft lip and palate. METHODS: For 100 fetuses diagnosed with cleft lip with or without palate, G-banding chromosomal karyotyping and copy number variation sequencing (CNV-seq) were carried out on chorionic villi, amniotic fluid or cordocentesis samples. RESULTS: No genomic abnormality was found among 49 fetuses with isolated cleft lip and palate, while 12 genomic aberrations were found among 51 fetuses with syndromic cleft lip and palate, which included 4 cases with trisomy 13, 2 cases with trisomy 18, 1 with X chromosome aneuploidy, 2 with other chromosomal aneuploidies and 3 with pathogenic CNVs. CONCLUSION: The incidence of genomic abnormalities in fetuses with cleft lip and palate was high. In addition to chromosomal abnormalities, attention should also be paid to pathogenic CNVs.
