Preimplantation    genetic   testing   for   monogenic disorders (PGT-M) is a genetic screening technique used during  in  vitro   fertilization  (IVF)   to  identify embryos with specific inherited genetic  conditions. It is particularly used for couples  at risk of  passing on monogenic disorders, such   as   cystic   fibrosis, sickle cell anemia, or Huntington’s disease.   PGT-M involves   extracting    cells    from    embryos     and analyzing  them for   known   mutations   associated with these conditions. The goal is to select embryos free of the genetic   disorder  for  implantation.  This procedure reduces the  risk  of  passing  on  genetic diseases to the child. PGT-M is typically   performed after embryo biopsy and genetic   analysis.  While  it can provide valuable   information,  it  requires  prior knowledge of the genetic mutation   in   the    family.
