概括

糖原储存疾病第九类 (GSD IX) 是由肝脏酸化酶b激酶 (PhK) 缺乏引起的. 大多数患者经历了肝扩张和肝酶升高,营养干预改善了生长并减少了低血糖症.

科学领域:

生物化学生物化学
遗传学是一个遗传学.
儿科内分泌学儿科内分泌学

背景情况:

糖原储存疾病第九类 (GSD IX) 是由于肝脏酶β激酶 (PhK) 缺乏导致的.
这种缺陷与PHKA2,PHKB和PHKG2基因中的致病变体有关.

研究的目的:

评估GSD IX患者的临床和生化特征.
评估长期结果和GSD IX. 的基因型-表型相关性.

主要方法:

来自三个欧洲国家的52名患者的临床和生化数据的回顾性分析.
对PHKA2,PHKB和PHKG2基因的遗传分析和酶检测.
评估患者的结果,包括生长,代谢参数和肝脏组织学.

主要成果:

GSD IXa占队列的86.5%;没有PHKA2变异导致严重的PhK缺乏.
常见的表现包括肝扩大 (82%),氨基转移酶升高 (81%) 和失脂症 (71%).
营养干预改善了生长和降低了低血糖症,尽管肝壮病经常持续;肝活检显示了,纤维化或慢性肝炎在52%.

结论:

GSD IX通常表现为肝扩大,肝酶升高和脂质失调,临床过程普遍有利.
严重的低血糖是不常见的,并且没有观察到明显的基因型-表型相关性.
营养支持有利于GSD IX患者的生长和低血糖管理.

Lysosomal Hydrolases

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
