As genetic tests allow us to know more about our
makeup than ever before, sorting out just how much information we want about
ourselves and our families can feel complicated – and perhaps nowhere is the
question more pertinent than when having a baby.
What do we want to know about a child’s risk of
disease? Most of us would agree that we would avoid passing on a fatal childhood
illness, such as Tay-Sachs, if we could. What about disorders that are serious
but not life-threatening? The answer of course will vary person by person. But
where people are in the family planning process can also make a difference.
Seeking out information as early as possible – ideally prior to conception – can
help parents-to-be feel empowered rather than anxious.
recent NPR story shared one couple’s experience with
expanded carrier screening during pregnancy to explore whether more information
is helpful or harmful. Test results indicated their baby could inherit spinal
muscular atrophy, leaving them worried and in search of a genetic counselor. Their
daughter was ultimately born healthy, but the experience was an added stressor.
Fortunately, there are ways to improve the screening experience and reduce the
likelihood of finding yourself in a similar situation.
First, consider preconception carrier screening. This allows you to talk about risk
and make an informed decision while it’s still hypothetical. Most
families will receive information that helps them worry less (97% of babies
born healthy, as the NPR article points out). For couples who learn they carry
the same recessive disorder, preconception screening provides more options for
having a healthy baby. Even those who don’t choose to alter their approach to
family planning can benefit from this knowledge by preparing for early intervention.
Second, ensure you have access to expertise. Consider
screening through a doctor’s office or community program – such as the one
offered by the Norton & Elaine Sarnoff Center for Jewish Genetics – that
includes genetic counseling as part of the pre- and post-screening process.
Before the test, education can help you understand what the test screens for
and the potential outcomes. Afterward, receiving results from a genetic
counselor or doctor with expertise in genetics ensures a thorough explanation
and an opportunity to ask questions.
Genetic counselors can also help you understand risk,
which often poses a challenge. Beyond understanding numbers and statistics,
it’s hard to take our feelings out of the equation and focus on facts with something
that feels so personal, like our health and the health of families. Genetic
counselors are trained in both medical genetics and counseling to empower you
with information and provide emotional support.
The journey to become a parent is exciting – and also
filled with many unknowns. Take away one by getting screened earlier and with
guidance from a genetic counselor.
