Can you show me more than 5 syndromes that are cause by dna mutation such as down syndrome, etc?

Here you go: Edwards syndrome, cre du chat syndrome, angelmann syndrome, turner syndrome, klinefelter syndrome, just to name 5 on the top of my head.

Down S not a DNA Mtn: Down syndrome is caused by an abnormality in the formation of the egg, when a pair of 21 chromosomes will end up as a triplet when conception occurs. Cystic fibrosis is an example of a dna mutation where a pair of abnormal genes don't have the information to control normal metabolic activities.There are thousands of possible metabolic abnormalities caused by gene mutations.
