Detailed analysis of 15q11-q14 sequence corrects errors and gaps in the public access sequence to fully reveal large segmental duplications at breakpoints for Prader-Willi, Angelman, and inv dup(15) syndromes

Abstract excerpt

BACKGROUND: Chromosome 15 contains many segmental duplications, including some at 15q11-q13 that appear to be responsible for the deletions that cause Prader-Willi and Angelman syndromes and for other genomic disorders. The current version of the human genome sequence is incomplete, with seven gaps in the proximal region of 15q, some of which are flanked by duplicated sequence. We have investigated this region by...
