What are the chances of inheriting fragile x syndrome? People with a full mutation (more than 200 repeats) have FXS. With each pregnancy, women have a 50% chance of passing fragile X on to their child (sons or daughters).
Is Fragile X Syndrome passed from mother or father? The gene for Fragile X is carried on the X chromosome. Because both males (XY) and females (XX) have at least one X chromosome, both can pass on the mutated gene to their children. A father with the altered gene for Fragile X on his X chromosome will pass that gene on only to his daughters.
Can a father pass fragile X to a son? Because the fragile X gene is located on the X chromosome, fragile X is never passed from father to son. However, a father passes his only X chromosome to all of his daughters, and therefore all daughters inherit his premutation. The number of CGG repeats is typically stable when passed from father to daughter.
Can a man pass on fragile X? Males can also carry the Fragile X premutation. A male carrier will pass his premutation (as a premutation, not a full mutation) on to all of his daughters and none of his sons. There is no reported risk for a male premutation carrier to have a daughter with Fragile X syndrome.

What is the underlying cause of angelman syndrome?
Angelman syndrome is caused by a genetic mutation on chromosome 15. The name of this gene is UBE3A. Normally, people inherit one copy of the gene from each parent, and both copies become active in many areas in the body. Angelman syndrome occurs when only one copy of the gene is active in certain areas of the brain.

How does hantavirus pulmonary syndrome cause thrombocytopenia?
Hantaviruses predominantly infect endothelial cells and cause acute thrombocytopenia in both HPS and HFRS patients (9, 17, 35, 37, 45, 64, 65). Endothelial cells line the vasculature and form a fluid barrier that is the primary determinant of capillary integrity and permeability (3, 19).
