Lynch Syndrome via MLPA of PMS2
Use
This test is for individuals with relevant features who have a clinical or suspected diagnosis of Lynch syndrome or constitutional mismatch repair deficiency, particularly those diagnosed with colorectal or endometrial cancer before age 50. It is also applicable for individuals with multiple Lynch syndrome-related cancers in close relatives diagnosed before age 50, those with tumor testing indicating microsatellite instability or loss of MMR protein expression, and individuals with negative PMS2 sequencing results but still showing clinical features of Lynch syndrome.
Special Instructions
Not provided.
Limitations
The test is based on Multiplex Ligation-Dependent Probe Amplification (MLPA), which may not detect all types of PMS2 pathogenic variants, such as deep intronic mutations or complex structural rearrangements not amenable to MLPA probes.
