Congenital hyperinsulinism is the most common cause of persistent hypoglycaemia in infancy. Early surgical intervention is usually required to prevent brain damage. The prevention of the transmission to the offspring is important in families carrying the mutated gene. Preimplantation genetic diagnosis (PGD) is an early genetic testing procedure for couples(More)
The discovery of cell-free fetal DNA (cfDNA) circulating in the maternal blood has provided new opportunities for noninvasive prenatal diagnosis (NIPD). However, the extremely low levels of cfDNA within a high background of the maternal DNA in maternal circulation necessitate highly sensitive molecular techniques for its reliable use in NIPD. In this proof(More)
OBJECTIVES Morquio syndrome is an autosomal recessive disease and mutations in the N-acetylgalactosamine 6-sulfate sulfatase (GALNS) gene cause Morquio type A disease. Preimplantation genetic diagnosis (PGD), an early form of prenatal diagnosis for couples at risk of transmitting inherited diseases, was applied to prevent transmission of this disease. (More)
Purpose:Our aim was to compare the accuracy of family- or disease-specific targeted haplotyping and direct mutation-detection strategies with the accuracy of genome-wide mapping of the parental origin of each chromosome, or karyomapping, by single-nucleotide polymorphism genotyping of the parents, a close relative of known disease status, and the embryo(More)
