I would like to indicate the excellent monograph of RIVA MILLER about GENETIC COUSELLING, written for the WFH.toh-25_english_genetic_counselling ! click and read it enjoying a intelligent and clear text.
X like X chromosome:
“X is the sex chromosome found twice in normal females = XX and once, along with a Y chromosome, in normal males = XY.”
The X chromosome carries hundreds of genes (informations about how you are going to be). Few, if any, of them have anything to do with sex.
The inheritance of genes on the X follows special rules because males have only a single X chromosome, and genes on the X are expressed in males.
Genes inherited in this manner are said to be sex-linked or, more precisely, X-linked. An example is Hemophilia A and hemophilia B.
A boy with hemophilia is Xh Y (the h is the hemophilia gene) and the carrier of hemophilia which is a woman will be XhX.
Sometimes both X in a woman can have the gene of hemophilia…this is very rare and is due to A MUTATION in the other X chromosome or in both. We have cases as I wrote in an old post, of women with hemophilia.
X chromosome
X COMO CROMOSSOMO X : “cromo = cor e somo/a= corpo…..O X é o cromossomo sexual que se encontra duas vezes no caso da mulher (XX) e uma vez só, junto ao Y no caso de um homen (XY).
Estes cromossomos carregan informações sobre muitas características suas…como se vai ou não ficar careca ou se vai ter algumas disfunções como por exemplo a Hemofilia A e a Hemofilia B.
São características ligadas ao X.
Uma mulher portadora da hemofilia terá a hemofilia ligada à um dos X (exemplo XhX onde o h é a hemofilia).
Um homem que tem hemofilia será XhY. No caso do homem a hemofilia se expressa porque o X é que está sozinho!
Algumas mulheres (muito muito raro!) são consideradas hemofílicas porque além de ser portadora , o outro X delas sofre uma mutação genética e não funciona direito em relação a produção do fator da coagulação 8 ou 9.
Lembrem que: quem tem hemofilia nasce com a informação (gen da hemofilia) que o fígado não poderá produzir fator 8 ou 9 o suficiente ou produz o fator mas ele não funciona! fazendo que a coagulação seja muito muito lenta

2) P-TET (Pediatric Thrombosis Educational Tool) , for kids on anti-coagulant treatment...inspired on IN-HEMOACTION flashcards success.
3) I am a co-author along with psychologist Irene Fuchs and Edward Kuebler of a booklet called "Communication, love and sexuality for people with hemophilia, carriers and family"
4) Done: systematic review for the Cochrane Collaboration :"psychological interventions for people with hemophilia and their families"
