Test Identifier Information

 
Registration CodeMPST
Method

The six coding exons of the MPZ gene are amplified using PCR and analysed by bidirectional fluorescent sequencing.

Diagnostic Use / Indications

MPZ sequence analysis is typically performed following a negative Hereditary Sensory and Motor Neuropathy MLPA analysis. Charcot-Marie-Tooth neuropathy type 1 (CMT1) is a demyelinating peripheral neuropathy characterized by distal muscle weakness and atrophy, sensory loss, and slow nerve conduction velocity.

Uncertainty of Measurement

 Automated bidirectional DNA sequencing has an analytical sensitivity and specificity of >99%. Note that the lower limit of variant detection of sequencing analysis is ~10%, this is important to consider in the case of mosaicism, mitochondrial, and somatic variation that is not expected to be present at 50% or 100%.  This analysis will not detect variants located within intronic regions, except at the intron-exon boundaries.

Additional Information
  1. This test requires nucleated cells. Please do not centrifuge or freeze blood samples.
  2. Genomic DNA must be extracted from the specimen prior to testing. This incurs an additional charge (see GDNA). Laboratories may prefer to submit DNA for testing. Please provide a minimum of 5 micrograms of DNA at 20 nanograms/microlitre.
  3. If storing blood tube prior to delivery please refrigerate at 4 degrees (transport still at ambient temperature).
