Detection of a subtle rearrangement of chromosome 22 using molecular techniques

Abstract excerpt

Conventional cytogenetics is a useful clinical tool that has a lower limit of sensitivity of 2-5 Mb for detection of duplications or deletions. Because the threshold of clinically significant aneusomy is below this range, there is a need for approaches to improve the sensitivity of the detection of aneusomy. We have implemented a system of screening for subtle unbalanced translocations in children with multiple...
