Adrenoleukodystrophy disorder is one of the x-linked genetic disorders caused by the myelin sheath breakdown in the brain. In this study, we present 4 yr experience on this disorder.
MATERIALS & METHODS: The patients diagnosed as adrenoleukodystrophy in the Neurology Department of Mofid Children's Hospital in Tehran, Iran from 2010 to 2014 were enrolled into the study. The disorder was confirmed by neuroimaging and clinical findings along with genetic and neurometabolic assessment at Reference Laboratory in Germany. We assessed age, gender, past medical history, developmental status, clinical manifestations, and neuroimaging findings of populous family with adrenoleukodystrophy.
All of the patients were one populous family with high rate of consanguineous marriages. This disorder was confirmed by genetic assessment, VLCFA and brain MRI. c.253_254insC, p.R85Pfs112* was found in heterozygote state and the VLCFA assessment showed the typical pattern for adrenoleukodystrophy/ adrenomyeloneuropathy. This diagnosis was in agreement with the family history and the clinical history of the patient. Since there have been a number of cases in patient's family in the past, so intensive follow-up on the family especially detection the female members of the family of childbearing age was recommended. The amount of C-26, C24/C22 and C26/C22 was elevated. All patients with the same genotype had wide ranges of clinical presentation.
Early diagnose of this disease might help us for early intervention and prenatal diagnosis for the disease in next siblings.
肾上腺脑白质营养不良症是一种由大脑中髓鞘破坏引起的X连锁遗传病。在本研究中,我们介绍了对该疾病4年的研究经验。
纳入2010年至2014年在伊朗德黑兰莫菲德儿童医院神经科被诊断为肾上腺脑白质营养不良症的患者。该疾病通过神经影像学和临床检查结果以及在德国参考实验室进行的基因和神经代谢评估得以确诊。我们评估了患有肾上腺脑白质营养不良症的大家庭的年龄、性别、既往病史、发育状况、临床表现和神经影像学检查结果。
所有患者均来自一个近亲结婚率很高的大家庭。通过基因评估、极长链脂肪酸(VLCFA)检测和脑部核磁共振成像(MRI)确诊了该疾病。发现杂合状态的c.253_254insC,p.R85Pfs112*突变,VLCFA评估显示出肾上腺脑白质营养不良症/肾上腺脊髓神经病的典型模式。这一诊断与患者的家族病史和临床病史相符。由于患者家族过去曾有过一些病例,因此建议对该家族进行密切随访,尤其是对育龄期女性家族成员进行检测。C-26、C24/C22和C26/C22的含量升高。所有具有相同基因型的患者临床表现范围广泛。
该疾病的早期诊断可能有助于我们进行早期干预以及对下一胎进行产前诊断。
