Diagnostic testing for genetic variants in the MECP2 gene associated with disorders such as Rett syndrome.
Special Instructions
Contact a Labcorp genetics coordinator at 844‑664‑8378 (844‑MNGTEST) with any questions.
Limitations
This assay may not consistently detect mosaicism or large chromosomal aberrations including rearrangements and inversions that do not change copy number; it does not detect repeat expansions. False positives or negatives may occur due to rare variants, sex chromosome abnormalities, pseudogene interference, homologous regions, blood transfusions, bone marrow transplantation, somatic or tissue‑specific mosaicism/heteroplasmy, mislabeling, or incomplete clinical information.
