1 One form of Stickler syndrome is due to mutation in the COL2A1 gene on chromosome 12 in region 12q13.11-q13.2. It is termed Stickler syndrome, type I and symbolized STL1.  A second form of Stickler syndrome is caused by mutation in the COL11A1 gene on chromosome 1 in region 1p21.
Recent technical advances in this field will give rise to conceptual advances and there is every reason to believe that a new field of cancer genetics is emerging, named here Oncogenetics: a branch of genetics describing the cause of effects of genes causing neoplasia.
There isn't really any difference. More like, epigenetics is a new and exciting kind of genetics. So, the traditional definition of genetics is that it comprises of all the properties that a living organism inherits from its parents. They stay the same throughout that organism's life and are subsequently passed on to the next generation.
