This is a data set obtained using the comparative genomic hybridization
technique (CGH) on samples from papillary serous cystadenocarcinoma
of the ovary. Only the seven most commonly occurring events are
given.
Usage
data(ov.cgh)
Format
A data frame with 87 observations on the following 7 variables.
8q+
a 0/1 indicator of the presence of the ‘8q+’ event
3q+
a 0/1 indicator of the presence of the ‘3q+’ event
5q-
a 0/1 indicator of the presence of the ‘5q-’ event
4q-
a 0/1 indicator of the presence of the ‘4q-’ event
8p-
a 0/1 indicator of the presence of the ‘8p-’ event
1q+
a 0/1 indicator of the presence of the ‘1q+’ event
Xp-
a 0/1 indicator of the presence of the ‘Xp-’ event
Details
The CGH technique uses fluorescent staining to
detect abnormal (increased or decreased) number of DNA copies.
Often the results are reported as a gain or loss on a certain arm,
without further distinction for specific regions. It is common to
denote a change in DNA copy number on a specific chromosome arm by prefixing
a “-” sign for decrease and a “+” for increase. Thus,
say, -3q denotes abnormally low DNA copy number on the q arm of
the 3rd chromosome.
