概括
这项研究没有发现中国患者面纤维发育不良症/ 麦昆- 阿尔布赖特综合征 (FD/ MAS) 的基因型- 现象型相关性. 最常见的是R201H变体,活跃的病变表明早期发病和潜在的并发症.
科学领域:
- 遗传学
- 癌症学
- 头骨面部生物学
背景情况:
- 纤维性发育不良症/麦昆-阿尔布赖特综合征 (FD/MAS) 是一种罕见的遗传性疾病.
- 了解基因型-表型相关性对于管理面性FD/MAS至关重要.
- GNAS基因突变与FD/MAS的发病有关.
研究的目的:
- 在中国的一群患有头骨面部FD/MAS的患者中研究基因型-表型相关性.
- 确定GNAS变种的流行情况.
- 确定影响疾病进展的预后因素.
主要方法:
- 对93例经组织学确认的FD/MAS病例 (2003-2024) 的回顾性分析.
- 直接测序GNAS突变.
- 临床数据 (发病,病变活动,骨外表现) 与基因型发现的相关性.
主要成果:
- 与R201C (41.9%) 相比,R201H是主要的GNAS变种 (58.1%).
- 活跃的病变 (34. 6%) 与早期发病,双边透,疼痛,鼻腔阻塞和麦库恩- 阿尔布赖特综合征 (MAS) 相关.
- 所有骨肉瘤病例 (3) 都携带R201C变异,这表明存在潜在的联系.
结论:
- 在该队列中没有发现FD/MAS的显著基因型-表型相关性.
- R201H是中国面FD/MAS患者的主要GNAS变体.
- 由于与早期发病,面参与和MAS相关,需要密切监测活跃病变;R201C需要进一步调查恶性转变风险.

Pleiotropy
41.1K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Cystic Fibrosis: Pathogenesis
358
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Sex-linked Disorders
103.0K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Genomic Imprinting and Inheritance
35.2K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...
