线粒体3 - - 3 - 甲基 - - 同酶A合成酶缺乏症 (HMGCS2D) 是一种罕见的遗传疾病. 大多数受影响的个体经历了代谢失补偿,但幸存者通常具有正常的神经发育.
科学领域:
- 生物化学 生物化学
- 遗传学 遗传学是一种遗传学.
- 代谢障碍 代谢障碍 代谢障碍
背景情况:
- 体对于大脑的能量供应至关重要.
- 线粒体3 - - 3 - 甲基 - - 同酶A合成酶缺乏症 (HMGCS2D) 是一种罕见的自体逆向性疾病,影响生成.
- 由HMGCS2基因中的双变异引起的,HMGCS2D已有有限的报告病例.
研究的目的:
- 综合分析所有报告和新确诊的HMGCS2D患者.
- 为HMGCS2D提供临床,生化和突变数据的概述.
- 在受影响个体中记录所有已识别的HMGCS2变异.
主要方法:
- 进行了彻底的文献搜索,确定了59个已发表的HMGCS2D.病例.
- 收集和分析了16名其他以前未被描述的患者的数据.
- 编制并讨论了临床过程,生化发现和突变数据.
主要成果:
- 总共分析了74名患者 (59名已发表+16名新患者).
- 大多数患者 (91%) 在婴儿期出现新生儿期以外的代谢失补偿.
- 幸存者的神经结果是有利的 (98%的正常发育),危机期间死亡率为8%.
- 在6个家族中发现了一个单一的常见变异 (NM_005518.4:c.634G>A,p.(Gly212Arg);没有建立基因型-表型相关性.
结论:
- 这项研究提供了对HMGCS2D患者数据的全面分析.
- 它包括在受影响个体中发现的HMGCS2变异的详细列表.
- 这些发现突出了HMGCS2D.的临床范围和结果.
