In 2009 couple with a serious problem visited INVICTA Fertility Clinic in Warsaw. Their first son was born with hereditary deafness. Having visited a genetic clinic parents recieved the information that their child’s illness is caused by genetic factors.
The patients learned that they were carriers of mutations responsible for the hearing loss only after the irregularities were found in their son. They reported to INVICTA with a query whether it is possible to eliminate the genetic disease in the next offspring. Adjusting the procedures and developing appropriate diagnostic methods require several months of engagement from a team of embryologists. The work, however, was successful and resulted in the birth of a healthy child.
The couple after proper verification was approved for the in vitro fertilization treatment and preimplantation diagnosis. Owing to specially developed method for the purpose, within the process it was possible to eliminate the risk of giving birth to another child with a genetic defect.
The birth of another child was burdened with 25% probability of an adverse configuration of genes. We evaluated them with the husband as a high despite the huge support of loved ones with the first son. On recieving the information about the program at INVICTA from a close friend, we decided right away – says Mrs Veronica, who decided to recieve the treatment.
Due to in vitro procedure, six embryos were obtained. All have been carefully tested in accordance with the methodology developed by the researchers. Only four of them were healthy. One of them was administered to Mrs. Veronica. The remaining three healthy embryos were frozen, while the other two due to inappropriate morphology and lack of cell division were not eligible for freezing.
After just two weeks, it turned out that I was pregnant, which, despite my active lifestyle was successful – says Mrs. Veronica. In the 38th week of pregnancy, a boy was born. The result of otoacoustic emissions test, routinely performed two days after birth, was correct. A month after birth, another specialized test was carried out, that confirmed the child’s appropriate responses in the auditory threshold.
Preimplantation genetic diagnosis is currently the only method enabling the diagnosis of genetic defects prior to its disclosure in the fetus or a newborn child. INVICTA Proprietary tests performed in order to eliminate the risk of congenital hearing loss in a child of a genetically loaded couples are the first in Poland. Two other clinics in the world perform similar diagnostics.
