Give me an example of It is observed that mutations in certain DNA repair genes such as ATM, ATR, XRCC4
are often associated with inherited brain developmental or functional abnormality, whereas
mutations in certain other DNA repair genes such as BRCA1, BRCA2 or TP53 are not
associated with any known inherited brain disorder.
Use whatever Internet (Google, ChatGPT, etc.) resources you need to generate three
hypotheses about why might mutations in certain DNA repair genes exhibit the brain-
related phenotypes whereas others do not. Write below these three hypotheses:
(a) 1 point
(b) 1 point
(c) 1 point
(d) Choose any one of the three hypotheses you have written above. Now, propose an
experimental test of your hypothesis using a mouse model and your knowledge of how
transgenic mouse can be made. There is no need to provide gory details.
