What Genetic Screening Looks For

Clarity Genetics has a comprehensive set of genetic screens — both single screens or sets of screens known as "panels." We offer two basic types of screens: carrier screens (which everyone can benefit from) and preimplantation screens (which are for couples pursuing in vitro fertilization). Everyone carries genetic conditions within their DNA. Clarity Genetics screens for the most common genetic conditions within any population to determine if you carry one of these and ultimately, to uncover your risk for passing it to your children.

What Genetic Screening Looks For

Discovering Your Genetic Inheritance

Every cell in our body carries two sets of genes — a set from each parent (one from the mother's egg and one from the father's sperm). Genes are made up of chromosomes, which are made up of DNA. And by looking at your DNA, screening can reveal your risk for carrying and passing along a gene or a chromosomal abnormality to your child. Genes can be either "recessive" or "dominant." The charts below show the possible outcomes depending on the genes of the mother's egg and those from the father's sperm.

Recessive Genetic Disease

A recessive genetic disease occurs when both copies of a particular gene have pathogenic variants. If you have one copy of a gene with a variant and one normal copy of that same gene, you are considered a "carrier" for that recessive genetic disease even though you are not affected by that disease.

In order for carriers to pass on a recessive gene, both partners would have to be carriers of the same genetic disease.

Dominant Genetic Disease

A dominant genetic disease occurs when one of the two copies of a particular gene has a pathogenic variant. Only one of the copies of the gene needs to have a pathogenic variant in order for an individual to be affected by a dominant genetic disease (recessive diseases require both copies to have variants). If either you or your partner have a dominant genetic disease, you run a 50% risk of having a child affected by that genetic disease.

X-Linked Disorders

The X and Y chromosomes (often called the sex chromosomes) determine whether a baby is male or female. Males have one X and one Y, while females have two X chromosomes. Some disorders are caused by variants or alterations of the X chromosome. Generally, if a woman has a pathogenic variant on one of the genes located on an X chromosome, she is considered a carrier — and has a 50% chance of passing that variant onto her children. If she passes on the variant on to a male child, that child can be affected with the condition. Affected males will not pass the variant onto their sons, but daughters of affected males will be carriers of the variant. Female carriers rarely develop symptoms of the condition but their daughters have a 50% chance of being carriers.

Which Screens Are Right for You?

Determining which screens or set of screens are right for you will depend on where you are in your reproductive journey. Tell us where you are today so you can learn more about how to move forward tomorrow.
