Quante persone sono colpite dalla Sindrome di Cohen? Ha la stessa prevalenza negli uomini e nelle donne? E nei differenti paesi?
Originale
It's considered rare because it has so many variables..because of its rarity there is not enough data to confirm any prevalence..it effects both boys and girls equally ...Being genetic means from birth..you don't catch or develop it..you are born with Cohen's Syndrome..
