RAI1 gene 17p11.2 deletion and duplication mutation analysis [Identifier] in Blood or Tissue by FISH Nominal

RAI1 17p11.2 Del+Dup Bld/T FISH

Definition

  • FISH studies are performed using an SMS probe to detect a deletion or duplication within the critical region of the retinoic acid induced 1 (RAI1) gene on chromosome 17p11.2. FISH signal pattern indicating a loss of the RAI1 critical region is consistent with a diagnosis of 17p11.2 deletion (Smith-Magenis) syndrome. Additional signals are consistent with a diagnosis of 17p11.2 duplication (Potocki-Lupski) syndrome. The answer list provided with this code is an example and not meant to include all possible results.
