Complex small supernumerary marker chromosomes (sSMCs) constitute one of the smallest subsets within the patients with an sSMC. Complex sSMCs consist of chromosomal material derived from more than one chromosome, for example, the derivative der(22)t(11;22)(q23;q11.2) in Emanuel syndrome. Here, a yet unreported case of a complex sSMC formed due to a t(7;9)(p22;q22)mat is presented.
small supernumerary marker chromosomes (ssmc) are still a major problem in clinical cytogenetics as they cannot be identified or characterized unambiguously by conventional cytogenetics alone. on the other hand, and perhaps more importantly in prenatal settings, there is a challenging situation for counseling how to predict the risk for an abnormal phenotype, especially in cases with a de novo ...
Sixteen newly established cell lines with small supernumerary marker chromosomes (sSMC) derived from chromosomes 1, 2, 4, 6, 7, 8, 14, 15, 16, 18, 19, 21, and 22 are reported. Two sSMC are neocentric and derived from 15q24.1-qter and 2q35-q36, respectively. Two further cases each present with two sSMC of different chromosomal origin. sSMC were characterized by multicolor fluorescence in situ hy...
