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.
Epigenetics: Fundamentals. What is Epigenetics? Epigenetics is the study of potentially heritable changes in gene expression (active versus inactive genes) that does not involve changes to the underlying DNA sequence â a change in phenotype without a change in genotype â which in turn affects how cells read the genes.
