Abstract：
Hypohidrotic ectodermal dysplasia (HED) is a genetic skin condition presenting as hypohidrosis, hypodontia, and hypotrichosis, resulting in an important burden for affected families. The most common form of HED has an X-linked inheritance and female carriers have the option of prenatal or preimplantation genetic testing (PGT) to avoid transmission of the disease. A combined PGT for a mutation in EDA gene and aneuploidies in a Mexican carrier of X-linked HED is reported.
Ovarian stimulation and assisted reproduction procedures were performed in a private academic medical center. PGT for a novel c.707-1G>A (rs886039466) mutation in EDA gene and chromosomal aneuploidies was performed by massive parallel and Sanger sequencing.
In the first PGT, the transfer of two blastocysts did not result in a pregnancy. An accumulative stimulation approach was decided to improve pregnancy chances for a second PGT procedure. Three ovarian stimulations were performed and 10 blastocysts coming from fresh and vitrified oocytes were genetically analyzed. A single embryo transfer produced a healthy non-carrier euploid girl.
PGT combining aneuploidy and mutation analyses is an alternative for female carriers of X-linked and other Mendelian disorders in Latin-American countries. In the era of genomic and personalized medicine, medically assisted reproduction techniques, such as PGT, are shifting from only infertility to preventive genetics.
