Please help with translocation

[Susan J. Kirkpatrick]

regarding the 9/20 translocation--a good medical genetics textbook can help
you with the basics of sorting out translocations and predicting possible
outcomes.  you'd have to do a search (medline can pull out chromosome info
under chromosomes, human, pair ___) to attempt to find literature about
frequency and phenotype.  Does your medical center have a genetic counselor
whom you can consult for help?
