HelpTest Code WILMP Hereditary Wilms Tumor Panel, Varies
Ordering Guidance
Customization of this panel and single gene analysis for any gene present on this panel are available. For more information see CGPH / Custom Gene Panel, Hereditary, Next-Generation Sequencing, Varies.
Targeted testing for familial variants (also called site-specific or known mutations testing) is available for the genes on this panel. For more information see FMTT / Familial Variant, Targeted Testing, Varies. To obtain more information about this testing option, call 800-533-1710.
If the reason for testing indicates WAGR syndrome (Wilms tumor, aniridia, genitourinary abnormalities, range of developmental delays), order CMACB / Chromosomal Microarray, Congenital, Blood.

Genetics Test Information
This test utilizes next-generation sequencing to detect single nucleotide and copy number variants in 9 genes associated with hereditary Wilms tumor: BLM, BUB1B, CDC73, DIS3L2, GPC3, REST, TP53, TRIP13, WT1. See Method Description and Targeted Genes and Methodology Details for Hereditary Wilms Tumor Panel for additional details.
Identification of a disease-causing variant may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling for hereditary causes of Wilms tumor.
