Is mutation frequency for Charcot-Marie-Tooth disease type 1 in the Chinese population similar to that in the global ethnic patients?
The mutation frequency for the Chinese CMT1 is similar to that seen in the global ethnic population. Molecular testing of the CMT1A duplication, along with the loci of MPZ and Cx32, may detect the majority of Chinese CMT1 patients.
Severely affected neonates with CDH have significantly smaller right internal jugular veins than other neonates. If the patient needs ECMO and if the internal jugular vein is too small for cannulation, the right brachiocephalic vein can be successfully cannulated from the neck instead.
