Thoughts and a few refs about CNV ================================== Questions: ========= History: Karyotypes, deletion mapping -- dates back to 1960s in humans! Autosomal Deletion Mapping in Man Walter E. Nance and Eric Engel Science, New Series, Vol. 155, No. 3763 (Feb. 10, 1967), pp. 692-694 1970s -- J. Stene did big (for those days) analyses of deletions, translocations, etc. in foetuses. Biology: What are they, How big are they (length distribution) How are they distributed in genome, Inherited/novel ? Technology How do we detect them. SNP genotyping arrays -- apparent homozygous segments, decreased/increased intensity (Illumina) Family data: apparent Mendelian errors. Health: Relationship to disease Causal or associated ? ---------------------------------------------------------------- A review paper: Zhang F, Gu W, Hurles ME, Lupski JR.
