First case of two supernumerary markers derived from chromosome 5 and chromosome 8
Abstract Background Small supernumerary marker chromosomes (sSMC) are additional il barone wine centric chromosome fragments too small to be identified by banding cytogenetics alone.A sSMC can originate from any chromosome and it is estimated that 70% of sSMC are de novo, while 30% are inherited.Cases of sSMC derived from chromosome 5 (sSMC5) are r
