Human germline engineering has two potential applications: prevent genetic disorders from passing to descendants, and to modify traits such as height that are not disease related. For example, the Berlin Patient has a genetic mutation in the CCR5 gene that suppresses the expression of CCR5.
Spermine is synthesized from the reaction of spermidine with SAM in the presence of the enzyme spermine synthase. The polyamines undergo rapid interconversion in the polyamine cycle, in which putrescine leads to synthesis of spermidine and spermine, with degradation of these polyamines to form putrescine, which can begin the cycle again.

Spermine is a polyamine involved in cellular metabolism that is found in all eukaryotic cells. The precursor for synthesis of spermine is the amino acid ornithine . It is an essential growth factor in some bacteria as well.
The SAT1 gene is 3,069 base pairs long. There are 171 amino acids and its molecular mass is 20024 Da (daltons). In 1992 at The Johns Hopkins University School of Medicine, Lei Xiao and several others cloned over 4000 base pairs of the region containing the coding sequence of the SAT1 gene also referred to as SSAT-1, SSAT, SAT, KFSD, DC21, KFSDX gene.

With the discovery of various types of immune-related disorders, there is a need for diversification in prevention and treatment. Developments in the field of gene therapy are being studied to be included in the scope of this treatment, but of course more research is needed to increase the positive results and minimize the negative effects of gene therapy applications.

Spermine synthase is an enzyme involved in polyamine biosynthesis. It is present in all eukaryotes and plays a role in a variety of biological functions in plants [ 3 ] Its structure consists of two identical monomers of 41 kDa with three domains each, creating a homodimer formed via dimerization .
