Plotting boxplots grouped by color in R

Below is my code to plot a box plot in ggplot2.I want to group the box plots by a type,so that all types are grouped together and colored.But I am still getting it mixed up.

p=ggplot(brcp.df,aes(variable,value)) + geom_point(shape=1) 
p + geom_boxplot(aes(fill=factor(type))) + geom_point(aes(color = factor(type)),outlier.colour="red") +geom_text(aes(label = gene) , size = 4,position = position_jitter(width = 0.6))

Do I need to add anything in my code above.For reference,below is my data.

 variable gene      value diagnosis     type      lQntl       uQntl     lBound    uBound
1 PM169_Z7 <NA> -0.1220775      CRPC Prostate -0.3693246 -0.02714948 -0.8825873 0.4861132
2 PM169_Z7 <NA> -0.4711975      CRPC Prostate -0.3693246 -0.02714948 -0.8825873 0.4861132
3 PM169_Z7 <NA> -0.5884106      CRPC Prostate -0.3693246 -0.02714948 -0.8825873 0.4861132

Thanks

As I commented:

library(ggplot2)
ggplot(brcp.df,
       aes(x = variable, 
           y = value)) + 
  geom_boxplot(aes(fill=factor(type)), 
               position = position_dodge(width = .8))

produces boxes of each type (here just 2) side by side:

enter image description here

I used 

brcp.df <- read.table(header=T, text="
variable gene      value diagnosis     type      lQntl       uQntl     lBound    uBound
