What do STAT proteins transcribe?
... In healthy individuals, STATs cause transcription of genes, however the transcription is turned off at the appropriate time. In LGLL, this process is dysregulated, and STATs continually transcribe target genes. This produces protein products that are now in excess and can cause harmful effects. ...

Point mutation
A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
