We report a 2-month-old boy with bilateral branchial cleft anomalies, low-set ears, and hydronephrosis who tested positive for a mutation in the TFAP2A gene (A256V) implicated in branchio-oculo-facial (BOF) syndrome.

By screening 1126 sporadic congenital heart disease (CHD) cases and 1227 controls, we identified 19 variants, including 5 unique non-synonymous sequence variations (N62S, R92G, T166N, G180-A187del and A187T) in patients.
We have demonstrated that the minor allele of rs34396413 was a risk factor of NTD in the Shanxi group, providing new insight into the study of NTD etiology.
The minor allele of rs34396413 significantly increased the risk of NTD in a Han Chinese population of Shanxi Province (P = 0.0082, OR = 1.45, 95%CI = 1.10-1.90), especially the risk of encephalocele for female (P = 0.0064, OR = 2.46, 95%CI = 1.22-4.94).

Prediction of SNP functionality revealed that the C allele in the C471T silent mutation (overrepresented in cases with CL(P) presents two putative exonic splicing enhancer motifs and creates a binding site AP-2 alpha, a transcription factor involved in craniofacial development.
