Table 1 Estimates for limits of duplicon containing CHRFAM7A

From: 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

  Segment(s) Genotype

  1. Segments are as defined in Figure 2. Genotypes are defined by a d allele (containing duplicon) or n allele (lacking duplicon). Copy numbers for each segment or junction as shown. '+' indicates the presence of each segmental junction.
