ORPHA:169808Clinical subtype
Also called Mild congenital F8 deficiency · Mild congenital factor VIII deficiency
What it is
A mild form of hemophilia A characterized by a small deficiency of factor VIII (biological activity between 5 and 40 IU/dL) leading to abnormal bleeding as a result of minor injuries or following surgery or tooth extraction. Spontaneous hemorrhages do not occur. Patients may be also labeled as having mild hemophilia A if they have a FVIII >40 IU/dL and a DNA change in the F8 gene and one of the following: (i) a family member with the same DNA change and FVIII of <40 IU/dL, and the DNA change is found in <1% of the population; and (ii) the international databases list the DNA change as being associated with hemophilia A and <40 IU/dL FVIII. The condition may affect males and female carriers of disease-causing mutations.

ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
