概括
甲基转移酶 (COMT) 和甲基网酸盐减少酶 (MTHFR) 基因中的低活性变异与青少年异常学脊椎病 (AIS) 的进展有关. 低COMT和MTHFR活性患者的AIS进展率显著更高.
科学领域:
- 遗传学 是一个遗传学.
- 整形外科 整形外科 整形外科
- 生物化学 生化学
背景情况:
- 异形脊柱脊椎病是一种复杂的脊柱形,具有显著的遗传成分.
- 甲基转移酶 (COMT) 和甲基网酸盐减少酶 (MTHFR) 的遗传变异已被单独与异常学脊椎病相关联.
- 在COMT和MTHFR中低活性变异对青少年异常学脊椎病 (AIS) 进展的综合影响仍未得到研究.
研究的目的:
- 研究COMT和MTHFR基因的低活性变体与青少年异常学脊椎病 (AIS) 的进展之间的关联.
- 为了比较AIS进展率在患者的组合低活性变体与中等或高活性变体的COMT和MTHFR.
主要方法:
- 一组72名被诊断患有AIS的患者,至少有两个青少年科布角测量,根据COMT (rs4680) 和MTHFR (A1298C,C677T) 基因型分为两组.
- 第1组包括具有COMT和MTHFR低活性变异的患者.
- 第二组包括具有COMT和MTHFR中等或高活性变异的患者. 进展被定义为科布角增加≥20度或脊柱手术. 分析使用了奇方位测试.
主要成果:
- 在72名患者中,有41人属于第一组,31人属于第二组.
- 在第一组的78.0% (32/41) 患者中观察到AIS进展,而在第二组的48.4% (15/31) 患者中观察到.
- 这两组之间进展率的差异在统计上是显著的 (p=0.009).
结论:
- 在COMT和MTHFR基因中具有联合低活性变异的患者表现出明显更高的AIS进展率.
- 这些发现表明,与COMT和MTHFR活动相关的特定遗传特征可能会影响AIS的进展.
- 对这些遗传因素作用的进一步研究可能会为AIS的新型治疗策略提供信息.

Pleiotropy
39.7K
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,...

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Nature and Nurture
20.4K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Translation
14.5K
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
