Document Summary
Avery welch dgs 3223 lab in cytogenetics week 1 module 1 notes 9/4/15: structural polymorphisms. Donor versus recipient in a bone marrow transplant. Inherited in a mendelian manner so can be used in family studies: determine whether an ambivalent abnormal finding may be abnormality variant/polymorphism or a. Other normal variations: breaks & gaps. Tabulated to keep track for q/c of lab. Patient condition usually induced with special media: weird chromosomes. More on karyotyping: a 1-3, b 4-5, c 6-12, x, d 13-15, e 16-18, f 19-20, g 21-22, y. How to karyotype: count, cut (careful: light vs. dark, identify (size/banding, place (p arm up, centromeres on line, analyze (band for band comparison) Karyotypes are presented in a standard form: the total number of chromosomes, comma, sex chromosome constitution, comma, any autosomal abnormalities.
