ABSTRACT
Objective@#To carry out genetic testing for a family with two pregnancies affected with hydrops fetalis and dilated cardiomyopathy (DCM) of the fetus.@*Methods@#DNA was extracted from fetal tissue as well as peripheral blood samples from the couple. Single nucleotide polymorphism array (SNP array) and next-generation sequencing (NGS) were carried out to screen potential mutation. Suspected mutation was validated with PCR and Sanger sequencing.@*Results@#The manifestation of fetal echocardiography was consistent with DCM. No obvious abnormality was found by SNP array analysis. A hemizygous c. 481G>A (p.G161R) mutation of the TAZ gene was detected in the male fetus by NGS and confirmed by Sanger sequencing. The mutation was inherited from his mother.@*Conclusion@#Barth syndrome due to the c. 481G>A mutation of the TAZ gene probably underlies the recurrent hydrops fetalis and fetal DCM in this family.
