Summary
This guideline reviews the role of uniparental disomy (UPD) in genetic diagnosis. It provides recommendations for clinicians and geneticists on when UPD testing is advised for constitutional genetic disorders.
Area of Science:
- Genetics
- Medical Diagnostics
Background:
- Uniparental disomy (UPD) is a complex genetic phenomenon.
- Understanding UPD's role is crucial for accurate constitutional genetic diagnosis.
Purpose of the Study:
- To provide a comprehensive review of UPD in constitutional genetic diagnosis.
- To establish guidelines for recommending UPD investigation in Canada.
Main Methods:
- Literature review conducted by CCMG committees (Cytogenetics, Molecular Genetics, Clinical Practice, Prenatal Diagnosis).
- Development of clinical guidelines for UPD testing.
- Circulation of guidelines for member comment and approval by the CCMG Board of Directors.
Main Results:
- A comprehensive review of UPD in constitutional genetic diagnosis was performed.
- Guidelines for UPD testing in Canada were developed and approved.
Conclusions:
- The developed guidelines aim to assist clinicians and geneticists in diagnosing genetic disorders.
- These guidelines standardize the recommendation for UPD investigation in Canada.

02:30Genomic Imprinting and Inheritance
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.

01:17Karyotyping
Describing the number and physical features of chromosomes can reveal abnormalities that underlie genetic diseases. This description is facilitated by special staining techniques that produce a particular banding pattern on each chromosome. State-of-the-art techniques make this approach even more powerful, enabling the detection of individual genes that cause disease.A Simple Chromosome Staining Technique Provides Valuable Scientific InsightSome genetic diseases can be detected by looking at...
01:21Nondisjunction
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold sister...
01:29Nondisjunction
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.
