Interin-linked kinase (ILK)is a kind of effector of intra-and extracellular biological signal transduction,partici-pating in the formation of multiple signal pathways,it plays an important role for occurrence and development of heart dis-eases such as cardiac hypertrophy,coronary heart disease,viral myocarditis,dilated cardiomyopathy etc..

Objective:To summarize the clinical manifestations, imaging characteristics, and diagnoses basis of adrenomyeloneuropathy (AMN).Methods:The clinical data of 3 patients with AMN, admitted to our hospital from November 2016 to April 2019, were retrospectively collected. The clinical manifestations, imaging features, and diagnostic process of these patients were analyzed.Results:Three young male patients had onset with gradual aggravation of unilateral or bilateral lower limb insufficiency. MR imaging showed symmetrical abnormal signals in brainstem in 2 patients, and atrophy of thoracic spinal cord in 1 patient. By target region capture sequencing, mutations in the ABCD1 gene were found in all 3 patients; 2 underwent pedigree validation; the remaining one patient and his mother had failed Sanger sequencing validation due to pseudogene interference, and elevated plasma level of very long chain fatty acid (VLCFA) was noted in this patient. Conclusions:AMN usually initiates in the adulthood with spastic paraplegia as onset. Symmetrical lesions in brainstem or atrophy of spinal cord can be manifested on MR imaging; some patients may be accompanied by adrenocortical insufficiency. The definite diagnosis mainly depends on genetic screening and determination of VLCFA level in the blood.
