Angelman/Prader Willi Syndrome by MS-MLPA
Use
This test is designed for individuals displaying features of Angelman syndrome, Prader-Willi syndrome, or 15q duplication syndrome. It also serves to confirm cases with a 15q11.2q13 deletion identified by other methods like chromosomal microarray or FISH. Such confirmations are crucial for precise diagnosis and treatment planning.
Special Instructions
This test has a turnaround time of 2 - 3 weeks. A STAT testing option is available, aiming for result delivery in 6 - 11 days. The test requires specific specimens and methods for accurate processing and results. Pre-counseling and informed consent are essential for patient understanding and data handling compliance.
Limitations
This test does not cover all possible genetic variations associated with Angelman, Prader-Willi, or related syndromes. It focuses exclusively on the detectable methylation patterns and potential deletions or duplications in the specific chromosomal region. Incomplete or degraded specimens might lead to inconclusive or false results. Additional tests may be recommended depending on clinical presentation and initial findings.
