A purpose-built high-resolution array with 93.75% breakpoint accuracy was used to map 4000 patients with diverse diagnoses and identify eight probands harboring microdeletions at TP53 (17p13.1), a DNA copy-number variations (CNVs) which might cause childhood-onset developmental delay (DD) and cancer. The results revealed a possible association of 17p13.1 CNVs with distinct phenotypes depending on the position of the breakpoint with respect to TP53 and called for further studies to determine if other loci in the genome also give rise to phentotypically distinct disorder.
