PG - 344-8 LID - 10.3760/cma.j.issn.1003-9406.2016.03.015 [doi] AB - OBJECTIVE: To explore the pathogenetic mechanism for a female patient affected with hemophilia A (HA). METHODS: Potential genetic defect was detected with inverse shifting-polymerase chain reaction (IS-PCR). The pattern of X chromosome inactivation was determined with a human androgen receptor assay (HUMARA assay). G-banded karyotyping was carried out to exclude potential chromosome aberrations. RESULTS: IS-PCR showed that the defect of FVIII gene was the distal type of intron 22 inversion. The HUMARA assay showed that the X chromosome inactivation was non-random, and that the mother's X chromosome activity was lower than that of the father's X chromosome which has carried the inverted FVIII gene. No abnormalities were found with G-banded chromosomes. CONCLUSION: The prevalence of female HA patient may be caused by non-random inactivation of X chromosomes.
