We used information provided by Carlos Flores & Bill Engels, University of Wisconsin, Madison, with stocks donated to the BDSC to estimate release 5 sequence coordinates for deficiencies carried in those stocks. These are their statements (from March 2004) followed by our estimates for each deficiency.
FBab0026816	Df(2R)50C-102
"Deletes from the middle of Cp1 proximally 10.2 kb into the longer transcripts of AGO1."
Estimated breakpoints in R5 sequence coordinates:   2R:9841630 ;9851830
R5 cytology corresponding to estimated sequence coordinates: 50C16;50C19
