supernumerary chromosome
Définition
- Humans typically have 22 pairs of autosomal chromosomes in their cells, and a pair of sex chromosomes. About 2.7 million individuals have an extra, 47th autosomal chromosome called a small supernumerary marker chromosome (sSMC). These small supernumerary marker chromosomes can originate from any of the 24 different human chromosomes. About 70% of the cases with sSMC are de novo (new mutations), 30% are inherited within a family. (Wikipedia)
