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 ...

The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
