BACKGROUND 17α-Hydroxylase deficiency(17-OHD)is a rare form of congenital adrenal hyperplasia,characterized by hypertension,hypokalemia,and gonadal dysplasia.However,due to the lack of a comprehensive understanding of this disease,it is prone to misdiagnosis and missed diagnosis,and there is no complete cure.CASE SUMMARY We report a female patient with 17-OHD.The patient was admitted to the Department of Neurology of our hospital due to limb weakness.During treatment,it was found that the patient’s condition was difficult to correct except for hypokalemia,and her blood pressure was difficult to control with various antihypertensive drugs.She was then transferred to our department for further treatment.On physical examination,the patient's gonadal development was found to be abnormal,and chromosome analysis demonstrated karyotype 46,XY.Considering the possibility of 17-OHD,the cytochrome P450 family 17 subfamily A member 1(CYP17A1)test was performed to confirm the diagnosis.CONCLUSION The clinical manifestations of 17-OHD are complex.Hormone determination,imaging examination,chromosome determination and CYP17A1 gene test are helpful for early diagnosis.
