Analytical Validity: Help
MLPA has greater than 99% sensitive for detecting deletion and duplication variants in case of more than one prob is in the affected area. Sensitivity reduces to 95% for the CNV's detected just one prob. Copy number changes detected by only a single probe always require validation by another method.
