Document the prevalence and

molecular characterization

of hemoglobinopathies in Hakka population of

the Meizhou region.

What said? Is true since the article??

Du RF, ed. (2004) The frequency of hemoglobin variantsin the Meizhou region is higher than the average of Guangdongprovince (0.368%, P,0.05).

Not

Xu XM, Zhou YQ, Luo GX, Liao C, Zhou M, et al.

Our study reveals a high prevalence of a/b-thalassemia in theregion, which is similar to the average level of Guangdongprovince (11.07%, P = 0.842).

Yes

Wang YZ, Jiang GA, Zhang JH, Su WJ, Chen HZ, et al.

The prevalence of hemoglobin variants in the Meizhou regionreported in this study (0.477%) is lower than that reported for thisarea 30 years ago (0.575%)

Not

Du RF, ed. (2004) In this study, the proportion of abnormal hemoglobin of the G/D group of the Hakka people in Meizhou is higher than that in thepearl river delta region, such as Guangzhou.

Yes

Is so important that in all countries, the

scientist begin to doing studies about this

diseases, because with this, we can get

better information about our people, and

for this medium determinate the

prevalence and the frecuency of the

talasemias, and give a better explain and

treatments to the relational diseases.

With the studies that was did, the scientists could get the variations in the hemoglobine, and wich were the estructural changes in each one of these, since some molecular testings.

The migration of the people, generated

new mutations in the hemoglobine, so if

the people travel around the world and

live in diferents countries, have a

posibility of that if have some type of

talasemia, this going to combine with

other type of talasemia.

In the families of now, the money is a

difficult topic, In some populations the

difficulties are largest, for this is so

important that the government, generate

programs to help this people, with money

to the sick.
