• trisomy
  • The mechanisms behind the formation of the RGMCs are unknown, but it could be hypothesized that RGMC formation is preceded by trisomy 12 or, alternatively, that ring formation of one chromosome. (lu.se)
  • rearrangement
  • The renovascular disease identified in this patient may be a direct consequence of the described chromosome rearrangement or a late clinical presentation in r(6) cases. (biomedcentral.com)
  • anomaly
  • Prenatal diagnosis may be offered to known del/ring carriers but risk calculations will be difficult since the meiotic behaviour of this type of anomaly is unknown in humans. (biomedcentral.com)
  • normal
  • The latter scenario would always result in isodisomy for the two normal-appearing chromosomes 12, whereas the former would yield isodisomy in one-third of the cases. (lu.se)
  • No embryos were completely normal or balanced for chromosome 22 by day 5. (biomedcentral.com)
