Test ID: UNIPD
Uniparental Disomy, Varies
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Evaluation of patients presenting with mosaicism, confined placental mosaicism, or Robertsonian translocations
Evaluation of patients presenting with features of disorders known to be associated with uniparental disomy (eg, Russell-Silver syndrome)
Evaluation of disease mechanism in individuals with rare autosomal recessive disease and only one carrier parent
Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request
Samples from fetus or child and both parents are required for analysis. Chromosome of interest must be specified on request form.
Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| CULFB | Fibroblast Culture for Genetic Test | Yes | No |
| CULAF | Amniotic Fluid Culture/Genetic Test | Yes | No |
Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
Uniparental disomy testing is available for all chromosomes. PCR and microsatellite markers on the chromosome of interest are used to test DNA from parents and child for the presence of uniparental disomy.
For prenatal specimens only: If amniotic fluid (nonconfluent cultured cells) is received, amniotic fluid culture/genetic test will be added and charged separately. If chorionic villus specimen (nonconfluent cultured cells) is received, fibroblast culture for genetic test will be added and charged separately.
