I would lean towards certain autosomal diseases such as CF having too small a mutation to significantly alter an entire karyotype. For instance, the most common mutation for CF is the delta508 mutation, which alters simply one base pair on the 508th base pair position on the transmembrane regulator gene (this mutation ultimately causes a dysfunction in transmembrane transport and causes the symptoms of CF disease).I might be confusing your question for something else but if you want just an image of the gene only that is altered, you can probably find one on the web. If I remember right, the chromosome altered is Chromosome 7 and you might want to look for the CFTR gene (cystic fibrosis transmembrane conductance regulator gene).EDIT: I looked up CFTR gene on Wikipedia and did find an image of the gene.Unfortunately, I haven't researched the other diseases you mentioned so I can't help you there
