the most comman cause of mental retardation is Fragile X chromosome or down synd?

  #2

I think It is Fetal Alcohol Syndrome!

  #3

Fetal alc synd is an imp cause of MR but not the leading cause.

the problem is that in on review I found it Fragile X ch, & it was Down synd in another one.

so wich of them is the one??


  #4

fetal alcohol syn....> most common cause of MR
fragile X syn..........>most common inherited(genetic) cause of MR.

  #5

1- Down Synd 2-Fragile X syndrome

Fetal Alcohol synd is the most common cause of preventable mental retardation

fragile x is the first one and before down, I remember this because even while studying for step 1 this was sort of strange for me.(but ininherited) and as prasannakumar says in general it is FAS.
