Order Fragile X Carrier Testing | Carrier ScreenFragile X syndrome is an inherited condition caused by changes in the FMR1 gene on the X chromosome. Fragile X carrier testing uses a blood sample to determine whether a person carries an expanded repeat in that gene, information that can be relevant to reproductive planning and to understanding the chance of passing the condition to a child.
About Fragile X Carrier Testing | Carrier Screen in Haltom City
Fragile X carrier screening examines the FMR1 gene for the repeat expansion that underlies fragile X syndrome.
The FMR1 gene normally contains a short, repeating sequence of DNA. When the number of repeats grows beyond a certain threshold, the gene can be silenced or its function altered, producing the features associated with fragile X syndrome. Testing measures the size of this repeat region and classifies the result, typically as normal, intermediate, premutation, or full mutation.
Because the gene sits on the X chromosome, inheritance patterns differ between males and females. A female with a premutation has a chance of passing an expanded repeat to a child, and the risk of expansion to a full mutation depends on the size of the premutation. A male with a premutation passes it to all of his daughters but to none of his sons. These patterns are why carrier status can matter even when a person has no symptoms.
Carrier testing is generally performed on a blood sample, and results are reported as a repeat-size range rather than a simple positive or negative. A healthcare provider interprets the result alongside personal and family history, since the implications for health and reproductive decisions vary by repeat size and by the individual's sex.
