Uniparental Disomy (UPD) Proband, DNA Analysis

This test code is reserved for proband testing of imprinted chromosomes only (6, 7, 11, 14, 15, 20). If non-imprinted chromosome testing is desired, please contact our Cytogenetics laboratory genetic coordinator group prior to collecting and submitting a sample (800-345-4363). Parental samples must be submitted in addition to the proband sample. A separate test code is used for parental samples. A separate test request form must be completed for each family member for whom a specimen is submitted. Blood specimens from both parents should be submitted using the parental UPD test code [470115]. The patient's name, age, and relevant clinical and family history should be included on the corresponding test request form. Please include chromosome pair to be studied. If cultured cells are needed, an additional 7-12 days may be required. Additional culture fee may be included.
