aneuploidia

I malati di questa sindrome sono femmine e sprovviste del Corpo di Barr. Sindrome del cri du chat — dovuta a una monosomia parziale: un cromosoma 5 dei due possiede, a causa di una delezione , un frammento del braccio corto in meno. Nella specie umana le cellule somatiche sono diploidi e hanno un corredo di 46 cromosomi appaiati in 23 coppie, tuttavia i gameti presentano una condizione aploide, con una sola copia di ogni cromosoma. Questo corredo cromosomico normalmente ha un uguale contributo da entrambi i genitori: nel caso in cui una coppia di cromosomi derivi da un singolo parente, si ha una disomia uniparentale. Nel caso estremo in cui tutti i cromosomi derivano da un solo genitore, si ha una diploidia uniparentale, che comporta il mancato sviluppo embrionale [2].
