Abstract:
The hallmark of neurofibromatosis type 1 (NF1) are multiple dermal neurofibromas. They show high inter- and intrafamilial variability for which the influence of modifying genes is discussed. NF1 patients presenting microdeletions spanning NF1 and several contiguous genes have an earlier onset and higher number of dermal neurofibromas than classical NF1 patients, pointing to one of the deleted genes as modifier. Expression analysis of 13 genes of the microdeletion region in dermal neurofibromas and other tissues revealed four candidates for the modification of neurofibroma formation: CENTA2, RAB11FIP4, C17orf79, and UTP6.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
