氨酸基转移酶 (APRT) 缺乏导致结石和功能衰竭. 早期诊断和用阿洛普醇或费布斯塔特治疗是有效和安全的,可以预防脏损伤并改善移植结果.
科学领域:
- 生物化学 生化学
- 遗传学 是一个遗传学.
- 腎臟病學 (nephrology) 是一種醫學專業.
背景情况:
- 氨酸基转移酶 (APRT) 缺乏症是一种罕见的纯素代谢遗传性疾病.
- 它导致2,8-二基氨酸尿路结石,水晶病,急性损伤 (AKI) 和慢性病 (CKD).
- 一些个体在成年后仍然没有症状.
研究的目的:
- 强调在患有特定症状的患者中考虑APRT缺乏的重要性.
- 强调诊断标准和确认APRT缺陷的测试.
- 审查在管理APRT缺乏症时的丁氧化还原酶抑制剂的疗效和安全性.
主要方法:
- 诊断依赖于通过基因检测识别双样致病APRT突变.
- 在患有,放射性石头,AKI或不明原因的CKD的患者中考虑APRT缺乏.
- 结石分析具有暗示性,但需要进行确认性遗传检测.
主要成果:
- 赞丁氧化还原酶抑制剂 (Allopurinol,Febuxostat) 是高度有效和安全的.
- 药物治疗可以减少石头的复发,减缓CKD的进展,并预防功能衰竭.
- 当患者接受适当的治疗时,移植的结果与衰竭的其他原因相比较.
结论:
- 及时诊断和治疗APRT缺乏症对于预防严重损伤至关重要.
- 艾洛普里诺和费布可斯塔特是治疗APRT缺乏症的有效治疗方法.
- 治疗APRT缺陷可以改善长期的结局和移植成功.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
