Preimplantation genetic testing for familial amyloid polyneuropathy

Reproductive Health, 2022
Background Embryo selection in Familial amyloid polyneuropathy eradicates the disease, but the widespread application of preimplantation genetic testing (PGT) for this monogenic disease still requires greater political and clinical commitment.

Embryo ploidy status classification through computer-assisted morphology assessmentAJOG MFM at a Glance

AJOG Global Reports, 2023
BACKGROUND: Preimplantation genetic testing for aneuploidy has been proven to be effective in determining the embryo's chromosomal or ploidy status. The test requires a biopsy of embryonic cells on day 3, 5, or 6 from which complete information on the ...

Prenatal mucopolysaccharidosis VII: A novel pathogenic variant identified in GUSB gene

Clinical Case Reports, 2021
Clinical exome sequencing is a powerful approach to overcome the wide clinical and genetic heterogeneity of mucopolysaccharidosis. These data could be useful for prenatal diagnosis of MPS VII, genetic counseling, and preimplantation genetic testing.

Pre-implantation Genetic Testing for Aneuploidy (PGT-A)

Thai Journal of Obstetrics and Gynaecology, 2020
Preimplantation genetic diagnosis (PGD) or embryo selection was first performed in 1989 using PCR for gender selection to avoid X-linked recessive disorder. However, there was a misdiagnosis due to allele drop out (ADO). Therefore, fluorescent in situ
