Factor X deficiency (X as Roman numeral ten) is a bleeding disorder characterized by a lack in the production of factor X (FX), an enzyme protein that causes blood to clot in the coagulation cascade. Produced in the liver FX when activated cleaves prothrombin to generate thrombin in the intrinsic pathway of coagulation.
For example, factor X deficiency may be seen in amyloidosis, where factor X is adsorbed to the amyloid fibrils in the vasculature. Deficiency of vitamin K or antagonism by warfarin (or similar medication) leads to the production of an inactive factor X.

Most individuals with G6PD deficiency are asymptomatic.When it induces hemolysis, it is usually is short-lived. [5]Most people who develop symptoms are male, due to the X-linked pattern of inheritance, but female carriers can be affected due to unfavorable lyonization or skewed X-inactivation, where random inactivation of an X-chromosome in certain cells creates a population of G6PD-deficient ...
Haemophilia A is a recessive X-linked genetic disorder resulting in a deficiency of functional clotting Factor VIII. [41] Haemophilia B is also a recessive X-linked genetic disorder involving a lack of functional clotting Factor IX. [44] Haemophilia C is an autosomal genetic disorder involving a lack of functional clotting Factor XI.
X-linked severe combined immunodeficiency (X-SCID) is an immunodeficiency disorder in which the body produces very few T cells and NK cells. In the absence of T cell help, B cells become defective. [1] It is an X-linked recessive inheritance trait, stemming from a mutated (abnormal) version of the IL2RG gene located on the X-chromosome.
AIRE is a transcription factor expressed in the medulla [broken anchor] (inner part) of the thymus. It is part of the mechanism which eliminates self-reactive T cells that would cause autoimmune disease. It exposes T cells to normal, healthy proteins from all parts of the body, and T cells that react to those proteins are destroyed.
The protein product of MAX contains the basic helix-loop-helix and leucine zipper motifs. It is therefore included in the bHLHZ family of transcription factors. It is able to form homodimers with other MAX proteins and heterodimers with other transcription factors, including Mad, Mxl1 and Myc.
