1. collect all cases of constitutional breakpoints in infertile and mentally retarded from Jena lab since 1998.
2. find out about repeatedly showing up breakpoints and iknclude in a seperate webpage.
3. provide data to find clusters of breakpoints in the human genome.
For inversions see also Human Polymorphic Inversion DataBase
Interestingly, 34 inversions (excluding inversions of chromosome 9 and Y) found in Taiwan were not overlapping with those collected here for Germany / (Middle) Europe apart from inv(2)(p11.2q13), known to evolve due to evolutionary peciluarities of chromosome 2 repeatedly in human population and inv(6)(p21.1q15) - seen in both studies only one time {14}.
This page is organized like the 'sister-page' on small supernumerary marker chromosomes (sSMC)
- the structure is explained here.
Also take care that the nomenclature here may not always be done exactly acc. to ISCN !!
