What's this test for?

This test is ideal if you or a family member has intellectual disability, developmental delay, or autism spectrum symptoms without a known cause. It's also useful for reproductive planning if there's a family history of these conditions, unexplained infertility, or recurrent miscarriage. The test looks for genetic and chromosome-level explanations that might be behind these concerns.

What happens after I get my results?

Your results will appear in your account with an explanation of what each finding means, including whether any FMR1 gene changes or chromosome differences were detected. Because this is a genetic test, next steps often involve reproductive planning or further family testing rather than lifestyle changes, and results are typically not something you retest regularly. A standard lab report is available to download directly from your account. If a result raises questions, review the explanation provided and consider reaching out to a genetic counseling resource for guidance on your specific situation.

What's included in this test?

This panel includes FMR1 gene analysis for CGG repeat expansion (with reflex methylation analysis if an expanded allele is detected) and chromosome analysis (karyotyping) for trisomies such as Down syndrome, sex chromosome abnormalities like Turner and Klinefelter syndromes, and structural rearrangements including translocations, inversions, and mosaicism at or above 14%. The FMR1 analysis helps identify Fragile X syndrome, Fragile X-associated primary ovarian insufficiency, and Fragile X-associated tremor ataxia syndrome. The chromosome analysis helps identify structural and numerical chromosome differences linked to intellectual disability, developmental delay, infertility, miscarriage, and birth defects.

How can I naturally support healthy pregnancy and reproductive planning?

While genetic results themselves can't be changed with lifestyle habits, supporting overall reproductive health can still help. Eating a balanced diet, taking a prenatal vitamin with folic acid, avoiding smoking and alcohol, and managing stress are all supportive habits during family planning. If results show an increased risk for a specific condition, discussing family planning options with a genetic counseling resource is a helpful next step.

When will I get my results?

Results for this panel are typically ready within about 7 days of your sample being received at the lab. Because this test involves detailed genetic and chromosome analysis, it takes longer than routine bloodwork. You'll be notified as soon as your results are available in your account.

Who should consider this test?

This test is a good option for individuals with unexplained intellectual disability or developmental delay, and for families who have a relative with these conditions. It's also relevant for women with early menopause-like symptoms, men with tremor or coordination issues later in life, and couples experiencing infertility or repeated miscarriage. Anyone doing reproductive planning who wants to understand their carrier status may also benefit.

What symptoms indicate I may need this test?

Signs that may point to needing this test include delayed speech or motor milestones in a child, learning difficulties, autism-like behaviors, or a family history of these traits. In adults, symptoms like early loss of ovarian function, hand tremors, or balance problems later in life can also be relevant. A history of unexplained infertility or multiple miscarriages is another common reason to consider testing.

What is Fragile X syndrome and why does it matter?

Fragile X syndrome happens when a specific gene called FMR1 has an unusually high number of repeated genetic letters, which can turn the gene off and affect brain development. It's one of the most common inherited causes of intellectual disability, especially in boys, and can also affect fertility and movement later in life for some carriers. Understanding your status matters because it can explain symptoms and inform decisions about future pregnancies.

What does an expanded FMR1 gene result mean?

An expanded result means you have more repeats than typical in the FMR1 gene, and the size of the expansion determines what it means for you. A smaller expansion (called a premutation) raises the risk of early menopause-like symptoms or tremor/balance issues later in life, while a larger expansion (a full mutation) is linked to Fragile X syndrome itself. The report will clarify which category applies and what reflex testing showed.

What should I do if my chromosome analysis shows an abnormality?

If your results show a chromosome difference, the report will describe exactly what was found, such as an extra chromosome or a rearranged piece. Next steps usually depend on the specific finding and may include reproductive planning conversations or testing of other family members. It's a good idea to keep a copy of your downloadable report handy for any future genetic counseling conversations.
