通过多基因面板,通过多基因面板确定遗传性偏角质瘤 (PGL) 和染细胞瘤 (PCC) 的风险. SDHA变异是常见的偶然发现,但在PGL/PCC患者中不太常见,需要进一步研究.
科学领域:
- 内分泌学 在内分泌学.
- 遗传学 是一个遗传学.
- 在瘤学瘤学.
背景情况:
- 大约30-40%的超结瘤 (PGL) 和染细胞瘤 (PCC) 有遗传性起源.
- 由于瘤的攻击性和相关的癌症风险,早期识别遗传风险至关重要.
- 这项研究侧重于患有PGL/PCC和/或遗传风险的患者.
研究的目的:
- 分析患有PGL/PCC和遗传风险的患者的临床表现和遗传史.
- 为了解这种罕见患者群体做出贡献.
- 评估多基因面板在识别遗传性PGL/PCC方面的实用性.
主要方法:
- 癌症遗传学诊所患者的回顾性图表审查 (2016年8月 - 2022年12月).
- 两个队列:在PGL/PCC基因中具有可能致病变体 (LPVs) /致病变体 (PVs) 的患者 (队列1) 和具有PGL/PCC个人病史的患者 (队列2).
- 对人口统计,个人/家庭病史和遗传检测结果的分析.
主要成果:
- 分析了560名患者 (队列1: 364,队列2: 269).
- 在第1组中,21.1%的人在PGL/PCC基因中有偶发的LPV/PV,主要在SDHx (46.8%),特别是SDHA (21名患者).
- 在第2组中,86名患者患有LPV/PV,最常见的是SDHx基因 (SDHB:24,SDHD:23).
结论:
- 多基因小组有效地识别患有遗传性PGL/PCC风险的患者,通常是偶然的.
- SDHA LPV/PV是常见的偶然发现,但在PGL/PCC患者中不太常见.
- 需要进一步进行纵向研究,以了解这些瘤的流行率和透率.

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...
Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.

Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports...
