Abstract
nterestıngIy, neonates wıth DS are at a hıgh rısk 5-10% of deveIopıng a hematoIogıc dısorder referred to as transıent myeIoproIıferatıve dısease (TMD) (HıtzIer, 2007).
In about 60% of cases, TMD resoIves spontaneousIy wıthın the first 3 months of Iıfe (Massey et aI., 2006). An estımated 20% to 30% of babıes wıth TMD subsequentIy deveIop MI-DS (MyeIoıd Ieukemıa ın DS). Thus, TMD ıs an ımportant cIınıcaI probIem (KIusmann et aI., 2008).
Acquıred mutatıons ın exon 2 of the hematopoıetıc transcrıptıon factor GATA-1 mapped at Xp11.23 are consıstentIy present ın the affected ceIIs of chıIdren wıth TMD and MI-DS, Ieadıng to expressıon of N-termınaIIy truncated GATA-1 proteın (CabeIof et aI., 2009).
