Zusammenfassung:OBJECTIVE: To identify novel genetic mutations in Chinese patients with congenital patent ductus arteriosus (PDA)
METHOD: Clinical data and peripheral blood specimens from a kindred spanning 3 generations in which 5 of 16 individuals had PDA and a cohort of 95 unrelated subjects with PDA were collected, and 100 unrelated healthy individuals were included as controls. The coding exons and flanking introns of TFAP-2B gene were amplified by polymerase chain reaction (PCR) with specific primers. We aligned the acquired sequences with which publicized in GenBank by the aid of program BLAST. Reverse transcription-polymerase chain reaction (RT-PCR) was used to amplify the parts of TFAP-2B and sequencing was performed on PCR products forward and reversely directly
RESULT: Sequencing of TFAP-2B identified that there was a splice-junction in intron 3 [intron 3(+5)G > A] and a 60 bp deletion was found in exon 3 by nested PCR. Additionally, a novel single nucleotide polymorphism (SNP) where a transition of guanine (G) to adenine (A) was identified at 34 bp front of transcription initiation site in TFAP-2B gene. There were significant differences in the prevalence of alleles G and A between controls and PDA patients (Z = -2.513, P = 0.012)
CONCLUSION: We identified a novel splice-junction in TFAP-2B gene which might lead to hereditary PDA in a Chinese family. However, the mechanism by which this mutation results in PDA is still to be ascertained
