DNA damage studies in cases of Trisomy 21 using Comet Assay
... Around 52 genes are identified on chromosome 21. Over-expression of these genes due to extra copy of 21st chromosome leads to increased level of oxidative stress lead-ing to DNAdamage which results in various clinical manifestations. Some of these are :Superoxide Dismutase (SOD1)- overexpression may ...
