概括
现在已经有了Noonan综合征 (NS) 的生长图表,显示NS患者的身高明显比普通人群更短,更轻. PTPN11突变与NS儿童的生长减缓有关.
科学领域:
- 遗传学 是一个遗传学.
- 儿科 儿科 儿科
- 内分泌学 在内分泌学.
背景情况:
- 努南综合征 (NS) 的生长模式尚未得到充分确定.
- 了解NS的生长对于临床管理和患者护理至关重要.
研究的目的:
- 为患有努南综合征的儿科患者开发生长参考曲线.
- 研究NS生长,遗传突变和临床表型之间的相关性.
主要方法:
- 在190名患有NS的儿童 (不包括接受生长激素治疗的儿童) 中进行了为期15年的回顾性观察性研究.
- 对身高,体重,BMI和身高速度的性别特定百分曲线的开发.
- 基因型分析以确定常见突变 (PTPN11,SOS1) 并与生长参数相关.
主要成果:
- 与意大利普通人口相比,努南综合征生长曲线显示身高和体重显著减少 (第50个百分位与第3个百分位对齐).
- 与其他突变患者相比,具有PTPN11突变的患者在5岁时的身高和体重较低.
- 在男性 (48.1%) 中,心血管异常 (85.3%) 和密码性异常 (48.1%) 的高患病率;心脏异常和PTPN11状态之间没有发现任何关联.

Polygenic Traits
65.7K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

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,...
