Six newly reported men evaluated in our institution with deletions in relation to the sequence of the Y-chromosome. (A) The palindromic structure encompassing the AZFb-c region. (B) The STSs used in the study: the tick marks show STS positions, ticks on the horizontal line denote single-copy STSs, and ticks down the horizontal line denote multicopy STSs. (C) Plus/minus STS results for the six infertile men with AZFb-c or AZFb deletions. Horizontal black bars indicate confirmed presence of the DNA, and minus signs indicate confirmed absence of the DNA region. Horizontal gray bars indicate multicopy STS positives that were disregarded because of cross-amplifying loci and negative results for flanking STSs. (D) Predicted and confirmed genes. (E) Apparently noncoding transcripts. Panels (A), (D), and (E) were according to Repping et al (6).
