Presentation
This study shows the feasibility of using CGH for the identification of supernumerary marker chromosomes, even in fewer than 50% of cells, where no clinical or cytogenetic clues are present. [ncbi.nlm.nih.gov]
The detail raw data are presented in [Table 1a] (presence: ; absence: -). Del(5q/20q), dir(9p/12p), -(18/19/Y), and, at least, one marker was consistently present in 88% of the cells evaluated. [cancerjournal.net]
Two important clinical characteristics which were commonly present in our case and other patients are developmental delay and microcephaly. [eymj.org]
Dyserythropoiesis was present, with megaloblastoid change and binuclear erythrocytes. Lymphoid aggregates and extrinsic cells were not present. Marrow fibrosis was not seen. Megakaryocytes were present, but reduced in number. [hoajonline.com]

Dual-color FISH images were digitally generated using the Isis FISH imaging software (MetaSystems). 300 cells were scored for each sample. FISH analysis showed a r(21) in 77% of examined cells and a monosomy 21 in 23% (300 cells investigated). [omicsonline.org]

Seizure medication is the first line of treatment to prevent seizures and stop seizure clusters. Some of the medicines used for this syndrome include: benzodiazepines, levetiracetam, valproate, phenytoin, phenobarbital, and lamotrigine. [epilepsy.com]
