Abstract Share this page

Preimplantation genetic diagnosis (PGD) has been applied for more than 200 different inherited conditions, with expanding application to common disorders with genetic predisposition. One of the recent indications for PGD has been inherited cardiac disease, for which no preclinical diagnosis and preventive management may exist and which may lead to premature or sudden death. This paper presents the first, as far as is known, cumulative experience of PGD for inherited cardiac diseases, including familial hypertrophic and dilated cardiomyopathy, cardioencephalomyopathy and Emery-Dreifuss muscular dystrophy. A total of 18 PGD cycles were performed, resulting in transfer in 15 of them, which yielded nine unaffected pregnancies and the births of seven disease- or disease predisposition-free children. The data open the prospect of PGD for inherited cardiac diseases, allowing couples carrying cardiac disease predisposing genes to reproduce without much fear of having offspring with these genes, which are at risk for premature or sudden death. Preimplantation genetic diagnosis (PGD) is currently an established clinical procedure in assisted reproduction and genetic practices. Its application has been expanding beyond traditional indications of prenatal diagnosis and currently includes common disorders with genetic predisposition, such as inherited forms of cancer. This applies also to the diseases with no current prospect of treatment, which may manifest despite presymptomatic diagnosis and follow up, when PGD may provide the only relief for the at-risk couples to reproduce. One of the recent indications for PGD has been inherited cardiac disease, for which no preclinical diagnosis and preventive management may exist and which may lead to premature or sudden death. We present here our first cumulative experience of PGD for inherited cardiac diseases, including familial hypertrophic and dilated cardiomyopathy, cardioencephalomyopathy and Emery-Dreifuss muscular dystrophy. A total of 18 PGD cycles for these disorders was performed, resulting in transfer in 15 of them, which yielded nine unaffected pregnancies and birth of seven disease- or disease predisposition-free children. The data open the prospect of PGD for inherited cardiac diseases, allowing couples carrying cardiac disease predisposing genes to reproduce without much fear of having offspring with these genes at risk for premature or sudden death.
