背景情况:
- 全球发育迟缓 (GDD) 经常与遗传原因有关,但确定哪些儿童需要进行遗传检测是具有挑战性的.
- 了解GDD遗传测试的特定临床指标对于及时诊断和干预至关重要.
研究的目的:
- 根据基因检测结果,比较患有GDD的儿童的临床和发育特征.
- 确定表明需要在患有GDD的儿童中进行遗传检测的关键临床特征.

Genetic Screens
4.8K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Genome-wide Association Studies-GWAS
12.0K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
