The computer you are reading this on is likely due for an upgrade, because its technology has improved markedly over the past couple of years. Similarly, if you had genetic testing performed a few years ago, that technology has evolved, too. At Texas Fertility Center, we employ the latest genetic testing options for our fertility patients.
TFC doctors and staff recently attended the annual meeting of the American Society for Reproductive Medicine (ASRM) in Boston, and visited with one of our genetic testing partners, Good Start Genetics. Dr. Kaylen Silverberg explains an exciting new breakthrough in gene sequencing in this short video:
“In the old days we thought that each partner would need to have the exact same genetic mutation in order to have a baby with a severe genetic disorder,” says Dr. Silverberg. “We now know that, in fact, that is not correct. For example, a woman can have any of the mutations that have been identified in cystic fibrosis; her partner can have any of the other mutations. If they get together and produce a baby, they would have a one in four chance of having a baby with cystic fibrosis.”
In order to minimize the risk of producing children affected with a variety of different genetic disorders, Texas Fertility Center employs two basic types of testing.
A Genetic Test with Breadth
Texas Fertility Center might order Counsyl genetic testing for couples planning to get pregnant, and interested in preconception testing. Counsyl offers a broad test for 109 single gene defects. The technology that Counsyl currently uses is called microarray testing.
A Genetic Test with Depth
Good Start Genetics uses a different technology to screen for genetic disease, called next generation DNA sequencing. Gene sequencing tests can detect minimal alterations in the genetic code that – despite their small size – can still produce dramatic abnormalities in children. This technology has not only allowed Good Start to identify couples at risk for having children with preventable genetic disease, but also has enabled them to detect new mutations involving genes such as the ones that can cause CF.
Genetic testing affects how we treat and diagnose infertility, and helps give parents reproductive options like never before. Contact us at Texas Fertility Center to arrange for genetic testing.
