Hello,
Your blog caught my eye because it has the word 'thalassaemias'. I carry this trait, without notable symptoms, except for yielding consistently peculiar blood tests. Of course, any family that has evidence of this trait has to emphasize the importance of genetic counseling. Also, anyone who has this trait should be cautioned against iron overload (which you allude to in your blog). Young women don't run this hazard but men and older women do. One more curiosity: there may be an association between this trait and the development of autoimmune diseases.
Since my family has both the trait and an elevated incidence of autoimmune disease, I found this interesting.
Thanks for translating from Italian--that would have been a challenge.
