Genomic analysis using high-density single nucleotide polymorphism-based oligonucleotide arrays and multiplex ligation-dependent probe amplification provides a comprehensive analysis of INI1/SMARCB1 in malignant rhabdoid tumors.

ABSTRACT:

Purpose

A high-resolution genomic profiling and comprehensive targeted analysis of INI1/SMARCB1 of a large series of pediatric rhabdoid tumors was done. The aim was to identify regions of copy number change and loss of heterozygosity (LOH) that might pinpoint additional loci involved in the development or progression of rhabdoid tumors and define the spectrum of genomic alterations of INI1 in this malignancy.

Experimental design

A multiplatform approach using Illumina single nucleotide polymorphism-based oligonucleotide arrays, multiplex ligation-dependent probe amplification, fluorescence in situ hybridization, and coding sequence analysis was used to characterize genome-wide copy number changes, LOH, and genomic alterations of INI1/SMARCB1 in a series of pediatric rhabdoid
