A de novo atypical ring sSMC(22) characterized by array CGH in a boy with cat-eye syndrome.
Haltrich I, Pikó H, Kiss E, Tóth Z, Karcagi V, Fekete G. Haltrich I, et al. Mol Cytogenet. 2014 Jun 5;7:37. doi: 10.1186/1755-8166-7-37. eCollection 2014. Mol Cytogenet. 2014. PMID: 24959203 Free PMC article.
Chromosome analysis revealed a mosaic karyotype with the presence of a small ring-like marker in 60% of cells. Array CGH detected approximately an 1,2 Mb single and a 0,2 Mb double copy gain of the proximal long arm of chromosome 22. ...CONCLUSIONS: The present repo …
