OBJECTIVE: To analyze clinical and genetic features of a family affected with Van der Woude syndrome.
METHODS: The umbilical cord blood of the proband and the peripheral blood of the parents were used for the whole exon sequencing to find the candidate gene.Peripheral blood of 9 members of the family were collected for Sanger sequencing verification, bioinformatics analysis and genotype-phenotype correlation analysis.
RESULTS: The proband was diagnosed with cleft lip and palate by ultrasound. His father and grandmother had hollow lower lip and all other family members did not have the similar phenotype. A missense c.263A>G (p.N88S) mutation was found in exon 4 of IRF6 gene in the proband, his father and his grandmother.The mutation was not found in other family members.
CONCLUSIONS: A missense c.263A>G (p.N88S) mutation in IRF6 gene probably underlies the pathogenesis of Van der Woude syndrome in the family and the mutation has been firstly discovered in China.
