Genetic Testing For Women – Is It Helpful Or Harmful?


Scores of females have concerns about ailments that skulk in their family trees. Factually, women are leading the pack in regards to requesting genetic info.

Females are the quintessential charioteers of the acquirement of medical care.

Genetic testing is prevalent in expectant mothers & those keen on bearing children. However, others worried about heritable sicknesses – crescent-cell anemia (a condition affecting RBCs), cardiovascular ailment & diabetes – to seek genetic info in large numbers.

What could Genetic Testing divulge?

Alongside diagnosis & forecasting of conditions, genetic testing could:

  • Ascertain whether patients carry gene mutations for requirements passing on to kids.
  • Assessing fetal health (whether there is a risk of some disorder being inherited).
  • Screening eggs on fertilization before implantations.
  • Screening newly born babies at risk of suffering heritable conditions which necessitate immediate treatment.

At-Home Test Kits

In case one does not want to visit a doctor due to privacy worries or residing in remote locations from genetic counseling centers, online firms provide home test kits for prevalent conditions like cancer of the breasts & colon, autoimmune disorders, heart disease & macular dystrophy.

Typically in genetic testing kits, one would be taking a blood test or oral swabs to be forwarded to the lab with costs differing between three to twelve hundred dollars.

However, one needs to be wary that several firms online are offering a heritable background for entertainment-related reasons rather than medically related purposes.

Many of these aren’t looking at the gene mutation factor, which is such a crucial constituent regarding ailments. Moreover, home testing might be inaccurate for several health problems like diabetes.

There isn’t any dependable screening in case of type II diabetes & ample could be told by merely looking at kin history.

How online genetic testing works

However, there is a lot to DNA tests than merely getting outcomes. Several tests are difficult to interpret due to the intricateness & multi-layering of the method. Also, not every laboratory has a skilled genetic counseling team for reading outcomes.

Genetic counselors advise that females having a kin history of conditions like muscular dystrophy, cancers of the breasts & uterus & Huntington’s disease must first seek their guidance to ensure that they are apt entrants for testing.

For instance, when being counseled for Alzheimer’s disease – that one might not get despite getting a +ve test outcome – a counselor at times finds that one is at a greater risk of developing a more avertable health issue like cardiovascular ailment.

Hence, they might advise a comparatively non-expensive analytical blood analysis testing alongside modifications in dietetic intake & lifestyles.

Undergoing Testing

In case one wants to get tested or seek counseling. The NSGC could furnish the counselor’s name & other information location-wise alongside parameters for selecting professionals & obtaining the best out of every session.

Counseling by itself could be costing around four hundred dollars & expenses of genetic tests ranging from seven hundred to four thousand dollars. In general, outcomes of genetic testing would become obtainable within a two to six weeks period. The physician could be asked for referrals & who might provide it cover in one’s health insurance plans.

The outcomes wouldn’t be affecting one’s rates since info. Regarding the testing is held confidential. Passing off the GINA by Congress three years back shields patients from being discriminated against by an insurance service provider or company based on genetic info. For several insurance plans, the GINA went into effect last month.

Who Must Undergo Genetic Testing?

Genetic testing isn’t for everybody & several of the conditions detected are atypical. The majority of the testing is aimed at races like crescent-cell anemia for the Afro-American race & Tay Sachs for Jews.

Also, testing for most cancer forms is pointless as almost ninety percent of these are not heritable.

In the case of several conditions like ALS – prevalently called Lou Gehrig’s disease – an affirmative outcome would not lead to improved therapy or prevention. In such cases, it is better not to be putting such patient types through this when all it would be doing is setting off a panic.

At times, too much info could be dire & every patient needs to be weighing the risks & gains of the information. He/ she would obtain from such tests & be prepared for dealing with it.

However, this might alter with medical advancements. Imminently, genetic testing would hover around FGS (whole genome sequencing) – a process that would be routinely done by the conclusion of a decade or so – allowing researchers in sequencing not merely one gene, like BRCA1, two mutations or mucoviscidosis carrier, however the entire DNA of the individual for getting a more detailed look at the medical issue he/ she might encounter. The costly process is presently being conducted on merely 4-5 individuals to date.

Prevalent Genetic Tests

Here is guidance about the most typical genetic tests & ones which one must be considering:

Down’s syndrome

It is a heritable condition occurring in 1 from every seven to eight hundred babies & causal to becoming mentally retarded, suffering from development delay & other issues for a lifetime.

Getting screened for Down’s syndrome is routinely done for antenatal care & obstetricians would classically conduct ultrasounds & doing blood analysis in the initial three months of gestation followed by a quad-screen blood analysis performed at fifteen to twenty weeks of pregnancy.

In case the test comes out affirmative, the subsequent strategy would be CVS (chorionic villus sampling), wherein the cells are gathered from maternal placental tissue at 9 to fourteen weeks or optionally amniocentesis following fifteen weeks, wherein amniotic fluid encasing the fetus is drawn with a needle introduced in the uterine region.

Who must be Undergoing the Test?

Older expectant mothers must undergo the test since the chances of conception of a Down’s syndrome infant in the mid-thirties are 1 in four hundred & for a woman in her mid-forties, the chances are 1 in thirty-five. Moreover, at greater risk are ones having Down’s syndrome kids & carrier male couple. Expectant mothers, irrespective of age, are screened for this disorder.

Advantages: Ninety-eight to ninety-nine percent accuracy has been observed in the case of amniocentesis & chorionic villus sampling.

Downsides: There’s a one from two hundred risk of a pregnant woman miscarrying due to having opted for amniocentesis & a one from a hundred chance from chorionic villus sampling.

Expenses: These duo methods are averaging around 1500 dollars that several insurers are covering.

Neural Tube Anomalies

These include the cleft spine, anencephalia, cranial hernia, gaps in the brain/ spinal cord, & amongst the most typical birth flaws.

They are identified during gestation by one of 3 tests:

  • Top-resolution ultrasounds post-eighteen weeks.
  • Amniocentesis
  • Administration of MSAFP blood testing at sixteen to eighteen weeks.

Who must be Undergoing the Test?

Females with a history of an unborn or born infant having neural tube flaws must opt for the test. Those having folic acid deficits are at a greater risk of developing such defects. Several expectant moms undergo 1 of the tests during routinely done antenatal care.

Advantages: A parent could arrange for the specialized medical assistance that infants having such flaws would require.

Downsides: Amniocentesis augments the risk of miscarrying.

Expenses: The MSAFP testing costs over 160 dollars & +/- range varying state-wise. Top-resolution ultrasounds cost three to five hundred dollars, while chorionic villus sampling & amniocentesis would be costing around 1500 dollars.

BRCA1, 2 Gene Mutation

These signify genes that make a woman more susceptible to developing breast cancer. These are tumor suppressor forms & mutations have been associated with heritable cancers of the ovary & breast.

The method is basic blood testing that could conduct in a physician’s clinic.

Who must be Undergoing the Test?

Gene mutations are prevalent in people from E. Europe, Ashkenazi Jewish lineage. Ones having a 1st-degree relation (mom, sis, or daughter) or duo 2nd-degree relations (aunty, grandma) identified with cancer of the breasts or ovaries must be considering this test.

Other females having duo 1st-degree relations identified with cancer of the ovary or breasts before hitting fifty must be considering this test.

Advantages: Finding out that one isn’t having the mutation would ease all worries & avert expensive preventative methods.

Downsides: In case the test result is affirmative, then anxiousness & depression could strike, for which counselors could assist in taking into consideration preventative measures like removal of ovary or breast.

Expenses: It could range from hundreds of dollars to 3200 dollars based on the level of testing done.

Cystic Fibrosis

An incessant heritable condition afflicts the lung & digestive system in around thirty thousand kids & grown-ups in the United States.

Perspiration test is the benchmark approach for diagnosing this condition & those suffering from this condition would be having augmented chloride levels in their sweat. Application of chemical for inducing perspiration is made on the legs or arms & then the collection of liquids done & forwarded for laboratory analysis.

Blood testing could ascertain whether one is carrying a single or more cystic fibrosis gene mutations & the number of replicas of each.

After an affirmative test outcome, the subsequent approach is genetic testing for checking what mutation one is having. Newly born babies in the majority of the states are routinely screened for CF.

Who must be Undergoing the Test?

Over ten million people in the U.S. who are asymptomatic are carrying the flawed CF gene. Blood testing aids in detecting a carrier who might be passing the condition on to the next generation.

For getting CF, a kid must be inheriting a replica of the flawed cystic fibrosis gene from mother & father. ACOG advises that every couple who plan to have a baby & expectant mothers must be having the genetic carrier test done.

Advantages: A carrier could be making a well-informed conclusion regarding family-planning with the assistance of genetic-counseling.

By getting their kid-tested, parents could unearth whether he/ she has the condition & due to what mutations. Earlier therapy & preventative measures are of assistance since symptoms primarily do not surface till degeneration has commenced.

Downsides: Getting a +ve cystic fibrosis identification is stress-ridden & could upset parents.

Expenses: Perspiration testing generally is costing around three hundred dollars at cystic fibrosis qualified centers.

Seeing twenty-three to ninety-seven mutations in carriers would generally be running around four hundred to five hundred dollars & checking for over 1500 mutations would cost about 2500 dollars.

Mutation tests for people who’ve been identified with cystic fibrosis could be conducted with a carrier panel; however, if it fails to find the mutations, then sequencing testing would be costing 2500 to 3200 dollars for different outcomes.

Sickle Cell Anemia

It is a heritable disorder causing a deficit in healthful RBC to convey ample O2 all through the body. Blood testing could be detecting the flawed hemoglobin type, which is causal to the condition. Routine screening of newly born babies for this condition is done.

Among expectant mothers, CVS or amniocentesis could spot sickle cell anemia.

Who must be Undergoing the Test?

The gene is prevalent in individuals of Mid-East, East-India, Africa, Mediterranean lineage. In the United States, Afro-American & Latino people are prevalently afflicted.

Mother & father ought to be carriers of the sickle cell gene to have a genetic condition for their infant. The asymptomatic carrier might be passing it on to the next generation. People having sis or bro with the state are at an augmented risk.

Advantages: A couple who has been identified with being a carrier could visit a genetic counselor for preventative info & therapy choices.

Downsides: If the screening is affirmative, additional testing is necessary for determining the sickle cell count. There are dangers of the woman miscarrying from getting screened by procedures like CVS & amniocentesis.

Hemoglobin testing could be running to around seventy-five dollars, whereas DNA testing is approximately three hundred dollars.
