چکیده
INSTRUCTIONS FOR USE This Medical Policy provides assistance in interpreting UnitedHealthcare benefit plans. When deciding coverage, the enrollee specific document must be referenced. The terms of an enrollee's document (e.g., Certificate of Coverage (COC) or Summary Plan Description (SPD) and Medicaid State Contracts) may differ greatly from the standard benefit plans upon which this Medical Policy is based. In the event of a conflict, the enrollee's specific benefit document supersedes this Medical Policy. All reviewers must first identify enrollee eligibility, any federal or state regulatory requirements and the enrollee specific plan benefit coverage prior to use of this Medical Policy. Other Policies and Coverage Determination Guidelines may apply. UnitedHealthcare reserves the right, in its sole discretion, to modify its Policies and Guidelines as necessary. This Medical Policy is provided for informational purposes. It does not constitute medical advice.

I-38: Chromosome Instability in The Cleavage Stage Embryo
Recently, we demonstrated chromosome instability (CIN) in human cleavage stage embryogenesis following in vitro fertilization (IVF). CIN not necessarily undermines normal human development (i.e. when remaining normal diploid blastomeres develop the embryo proper), however it can spark a spectrum of conditions, including loss of conception, genetic disease and genetic variation development. To s...
متن کاملThe False Discovery Rate in Simultaneous Fisher and Adjusted Permutation Hypothesis Testing on Microarray Data
Background and Objectives: In recent years, new technologies have led to produce a large amount of data and in the field of biology, microarray technology has also dramatically developed. Meanwhile, the Fisher test is used to compare the control group with two or more experimental groups and also to detect the differentially expressed genes. In this study, the false discovery rate was investiga...
متن کاملDevelopment of SNP microarray for supplementary paternity testing
We have developed a SNP microarray for paternity testing, which contains 10 SNPs and in addition X and Y chromosome-specific markers. SNPs were selected with an emphasis on their high allele frequency in the Finnish population. Coding regions of known genes were excluded. With this setup of SNPs, we have calculated the average exclusion power in paternity testing to be 86.5%. The array was vali...
متن کاملSystematic review of accuracy of prenatal diagnosis for abnormal chromosome diseases by microarray technology.
The accuracy of prenatal diagnosis for abnormal chromosome diseases by chromosome microarray technology and karyotyping were compared. A literature search was carried out in the MEDLINE database with the keywords "chromosome" and "karyotype" and "genetic testing" and "prenatal diagnosis" and "oligonucleotide array sequence". The studies obtained were filtered by using the QUADAS tool, and studi...
متن کاملPrenatal diagnosis of a 46,XX male following noninvasive prenatal testing
Case report involving a normal female by NIPT with male external genitalia on routine fetal morphology assessment. QF-PCR, CGH microarray, and FISH revealed an unbalanced translocation, involving the short arms of the X and Y chromosomes. This case demonstrates the possible limitations of correctly identifying sex chromosome abnormalities via NIPT.
