生殖系SUFU致病变体 (PVs) 与惰性基底瘤和基底细胞癌有关,通常在中年出现. 这扩大了我们对基底细胞神经综合征 (BCNS) 的理解.
科学领域:
- 皮肤病学 皮肤病学
- 遗传学 遗传学 是一个
- 在瘤学瘤学.
背景情况:
- 已知生殖系SUFU的致病变体 (PVs) 会导致基底细胞神经综合征 (BCNS) 和多发性基底细胞癌综合征.
- 与SUFU PVs相关的皮肤发现的全谱需要进一步划分.
研究的目的:
- 确定生殖线SUFU PVs患者皮肤发现的临床和组织病理谱.
主要方法:
- 在美国学术皮肤病学,医学遗传学和医学瘤学诊所进行的案例系列 (2014年7月至2022年7月).
- 包括由皮肤科医生评估的确诊生殖线SUFU PVs的患者.
- 皮肤活检和瘤样本的下一代向测序 (NGS) 的组织病理学评估.
主要成果:
- 五名女性患者在31-68岁 (平均50.2岁) 之间出现了皮肤表现,主要是在他们的第四到第六十年.
- 病理学揭示了基底性毛囊性瘤 (BFHs),体囊性基底细胞癌 (iBCCs),结节性基底细胞癌 (nBCCs) 和透性BCC.
- 与BFH相比,NGS建议在BCC中增加紫外线签名变体.
结论:
- 生殖线SUFUPVs可以表现为多个惰性基底瘤与常规BCC一起,与PTCH1BCNS不同.
- 皮肤病学家和皮肤病理学家应该认识到这一频谱,因为许多病变是惰的,可能不需要积极的治疗.
- 针对光滑化 (SMO) 的疗法不太可能是有效的,因为SUFU在路径中的下游位置.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
