COMMENT
Avoid cryopreservation.
Repeat expansions related to SCA1, SCA2, MJD/SCA3, SCA6, SCA7, SCA8, SCA12, SCA17, DRPLA and expansion insertions related to SCA31 and thePLEKHG4 gene. c.-16 is being analyzed. Please avoid duplicate requests with other items. This testing method has a greater effect of contamination, so please be careful when handling the specimen.
Subject to ethical guidelines (see below)
Collect blood into the container shown below, mix well, and store in the refrigerator. Avoid duplicate requests for other items. This testing method is sensitive to the effects of contamination. The sample is larger, so please be careful when handling it when collecting the sample.
