Pregnancy and Radiation Exposure Information Sheet is an information sheet published by the Health Physics Society. The same cohort was then divided into subjects diagnosed with EP vs. (IUP + SAB). Because karyotype analysis does not help in detecting abnormalities caused by single gene mutations or mutations at several loci (small structural deletions and rearrangements), different techniques, such as fluorescence in situ hybridization (FISH), are being used to complement standard cytogenetics.
