A detailed explanation of the PGT[M]Seq method and its requirements is given in the Juno Genetics User Manual. In brief, Juno can begin work on a new PGT[M]Seq test once it has received the following: 1) a genetic report describing the mutation(s) responsible for the disorder for which PGT[M]Seq is being requested; 2) blood samples from the couple requesting PGT[M]Seq (both the man and the woman, even if only one of them carries a mutation); 3) where possible a sample from a child or other close relative who has been tested for the mutation (blood, DNA or saliva); 4) a completed Requisition Form, confirming the request for PGT[M]Seq and providing relevant information concerning the patients. In rare cases, PGT[M]Seq is not technically possible. Additionally, PGT[M]Seq often requires several weeks in order to develop and validate a new test. For these reasons, patients should not begin a cycle until Juno has confirmed that a PGT[M]Seq test has been successfully developed.
