The six largest pairs of autosomes were biarmed and varied in centromere position from metacentric to subtelocentric.
At that time, when mammals were evolving from their common ancestors with reptiles and birds, what are now the X and Y chromosomes were a pair of autosomes similar to today's X chromosome.
The present study revealed a rare de novo sex autosome translocation in a female with primary amenorrhea.
The first pair of autosomes is acrocentric and distinctly larger, but the rest of the autosomes form a graded series from medium to small-sized acrocentric elements.
We determined the relative PLP1 and X-chromosome copy numbers from peak areas by normalizing each PLP1 and X-chromosome-specific probe to each autosome, using normal female DNA as a calibrator.
This can be done through identical analysis of a second, placentally expressed gene from a different autosome (placenta-specific reference gene).
For human DNA (except for the sex chromosomes), a PCR product usually represents amplification from two alleles, one of each autosome of a pair.
To detect such aneuploidies, we designed 2 types of assays: XA assays, which we used to indicate the ratio between the X chromosome and a given autosome, and XY assays, which we designed to indicate the ratio between X and Y chromosomes.
including only samples with diploid karyotypes for chromosomes 21,18,13, and X) and considered each autosome as a potential denominator in a ratio of counts with our chromosomes of interest.
Also, variation in the number of arms of the autosomes, such as observed in the material from El Salvador, often signals specific differences.
