I have become confused about mode of inheritance of fragile x syndrome .. as far i know from goljan and my knowledge its a x-linked recessive disease but in the kaplan video lecture of genetics the old guy is saying its a good example of x linked dominant disease ..which one is correct.can anybody please clear my confusion ?

  #2

i was under the impression that XLR is usually passed from mom to son, and that XLD is from father to daughter, so it makes sense that Fragile X is XLR (and a triple repeat disorder); i too have alwys heard x-linked recessive; i thought the only x-linked dominant was one form of rickett's and pseudohypoparathyroidism, no??

hope i helped and didn't confuse u more! shocked

  #3

thats a lot ..I also think its XLR . And XLD diseases are familial hypophosphatemia and alport's syndrome .

  #4

crap, haha.. i knew it was hypo- something, hahha.. alports huh?? hmm, interesting, thanx for that!! nodnodnod

hey i saw u msg, my exam rite now is scheduled for 22, but i may have to move it confused

not sure yet, havnt just sat down to focus, which i need to do, so have been doing goljan daily with sutdy partner, but not yet doing FA which i should do.. and totally stopped questions.. i am doing usmlerx which goes with FA so i had hoped i would cover it with that.. but have not been doing questions either..

we shall see.. when is u test?

I thought that fragile X syndrome follows Nonmendelian inheritance pattern, so it is not X -linked at all...
