Hi Peng, The IDs were originally just a number, but letters were added to increase the amount of items we could represent. IDs are assigned as genes are added, so two related genes could have dissimilar IDs if they were added at different times. The '.#' represent variations of the gene. I hope this answers your questions. Please feel free to contact us again.
