Objective: a fetus with a ring chromosome 20 is presented. Methods: at 16 weeks’ gestation, ultrasound examination evidenced no apparent structural malformation. Amniocentesis was performed for maternal anxiety. Results: chromosome analysis identified a ring chromosome 20 and array-CGH demonstrated that the ring including micro-deletion of the short arm in 20p13, that was extended for about 632...

The chromosome numbers and karyotypes of eight species the genus Allium distributed in Turkey were analyzed. These taxa are A. armerioides Boiss., orientale stamineum tuncelianum (Kollmann) Özhatay, B.Mathew & Şiraneci, subakaka Razyfard Zarre, muratozelii Armağan, dumanii Koyuncu Koçyiğit colchicifolium Boiss. Four them (A. armerioides, tuncelianum, dumanii) endemic Turkey. all studied determi...

Autosomal dominant polycystic kidney disease is a heritable disorder and recent studies have shown genetic heterogeneity, with some, but not all, families showing linkage with markers on chromosome 16p. Members of a large ADPKD family, unlinked to chromosome 16, have been typed for 12 marker loci located on both arms of chromosome 1. Multipoint analysis excluded ADPKD2 from the region between D...

The functional human metallothionein (MT) genes are located on chromosome 16q13. We have physically mapped the functional human MT locus by isolation and restriction digest mapping of cloned DNA. The mapped region contains all sequences on chromosome 16 that hybridize January 7, 2006 2:28 Proceedings Trim Size: 9in x 6in baldwin

We have utilized a combination of conventional and spectral karyotyping (SKY) techniques and allelotype analysis to assess numerical and structural chromosome alterations in two cell lines derived from normal human prostatic epithelium, and three cell lines derived from human prostate primary tumor epithelium, immortalized with the E6 and E7 transforming genes of human papilloma virus (HPV) 16 ...
