Overview of repeats
When Rauch et al. (2010) were analysing patients with tetralogy of fallot (TOF) heart disease, they discovered one individual with repeat expansion in the TBX gene. The allele was expanded from 15 to 25 repeats of alanine and none of the 185 controls nor patient's mother had the expansion (Rauch et al., 2010).
