AbstractBetween 1981 and 1990, 765 symptomatic neonates with major congenital heart malformations were admitted into the Grantham Hospital. This represented an incidence of 10 per 10,000 live births for Hong Kong. The figure was comparable to those reported for Caucasians. Among the 744 Oriental neonates, obstruction of the pulmonary outflow tract occurred most frequently (281, 37.8%), followed by left ventricular outflow tract obstruction (169, 22.7%), left-to-right shunting (115, 15.5%), complete transposition (92, 12.4%), common mixing situations (62,8.3%), and miscellaneous causes (25, 3.3%). When compared with the available reports from the West, Chinese neonates had a high preference for pulmonary outflow tract obstruction (p<0.005), especially the anomaly of pulmonary atresia and intact ventricular septum. This correlated well with cyanosis as the commonest neonatal presentation (64%). Contrary to previous reports that aortic coarctation was rare among Orientals, this abnormality was observed frequently in our study. The rare occurrence of critical aortic valvar stenosis among Chinese, however, was supported by our present analysis. Other lesions, such as left-to-right shunting and complete transposition, showed no significant racial difference in the frequency of occurrence. Such knowledge concerning the pattern of congenital heart disease amongst Oriental neonates can facilitate early diagnosis and timely referral of babies to the appropriate center for management.

ABSTRACTCongenital heart disease is the most common birth defect in newborns and the leading cause of death in infancy, affecting nearly 1% of live births. A locus in chromosome 4p16, adjacent to MSX1 and STX18, has been associated with atrial septal defects (ASD) in multiple European and Chinese cohorts. Here, genotyping data from the UK Biobank was used to test for associations between this locus and congenital heart disease in adult survivors of left ventricular outflow tract obstruction (n=164) and ASD (n=223), with a control sample of 332,788 individuals, and a meta-analysis of the new and existing ASD data was performed.The results show an association between the previously reported markers at 4p16 and risk for either ASD or left ventricular outflow tract obstruction, with effect sizes similar to the published data (OR between 1.27-1.45; all p<0.05). Differences in allele frequencies remained constant through the studied age range (40-70 years), indicating that the variants themselves do not drive lethal genetic defects. Meta-analysis shows an OR of 1.35 (95% CI: 1.25-1.46; p<10−4) for the association with ASD.The findings show that the genetic associations with ASD can be generalized to adult survivors of both ASD and left ventricular lesions. Although the 4p16 associations are statistically compelling, the mentioned alleles confer only a small risk for disease and their frequencies in this adult sample are the same as in children, likely limiting their clinical significance. Further epidemiological and functional studies may elicit factors triggering disease in interaction with the risk alleles.

Abstract Congenital heart disease is the most common birth defect in newborns and the leading cause of death in infancy, affecting nearly 1% of live births. A locus in chromosome 4p16, adjacent to MSX1 and STX18, has been associated with atrial septal defects (ASD) in multiple European and Chinese cohorts. Here, genotyping data from the UK Biobank was used to test for associations between this locus and congenital heart disease in adult survivors of left ventricular outflow tract obstruction (n = 164) and ASD (n = 223), with a control sample of 332,788 individuals, and a meta-analysis of the new and existing ASD data was performed. The results show an association between the previously reported markers at 4p16 and risk for either ASD or left ventricular outflow tract obstruction, with effect sizes similar to the published data (OR between 1.27–1.45; all p < 0.05). Differences in allele frequencies remained constant through the studied age range (40–70 years), indicating that the variants themselves do not drive lethal genetic defects. Meta-analysis shows an OR of 1.35 (95% CI: 1.25–1.46; p < 10−4) for the association with ASD. The findings show that the genetic associations with ASD can be generalized to adult survivors of both ASD and left ventricular lesions. Although the 4p16 associations are statistically compelling, the mentioned alleles confer only a small risk for disease and their frequencies in this adult sample are the same as in children, likely limiting their clinical significance. Further epidemiological and functional studies may elicit factors triggering disease in interaction with the risk alleles.
