A novel mutation at the AMEL primer binding region on the Y chromosome in AMELY negative male.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Gender identification in forensic DNA typing is an important tool for criminal investigation as well as STR typing. Most methods are based on a size difference of amelogenin X and Y (AMELX and AMELY). There have been some reports that the method by amelogenin (AMEL) incorrectly typed some males as females because the AMELY allele is not detected. AMELY allele dropout is often caused by deletions encompassing AMELY on Yp11.2 and accompanied with Y-STR allele dropout (especially DYS458). However, an unusual deletion was found in our laboratory. The AMELY allele could be recovered by using another commercial kit and alternative AMEL primer sets, and the Y-STR markers resulted in a complete profile. Sequencing results showed that there was an 8 bp deletion in AMELY at the position corresponding to 41-48 bp downstream from the 3' end of the 6 bp deletion site in AMELX. This is considered a novel mutation at a primer binding region.
