概括
在男性中,WNT3 rs3809857的多态性显著降低了仅唇裂 (NSCLO) 的风险. 性别是影响非综合征性口腔裂 (NSOFC) 的基因易感性的关键因素.
科学领域:
- 遗传学
- 遗传性缺陷
- 人口研究
背景情况:
- 非综合征性口腔裂 (NSOFC) 是越南常见的先天性缺陷,每1000名新生儿中就有1.4名出现这种缺陷.
- 在NSOFC的发生方面存在明显的性别差异.
- 研究遗传因素及其性别特异性相互作用对于理解NSOFC病因至关重要.
研究的目的:
- 调查越南NSOFC亚型中WNT3和NOG基因多态的潜在性别特异相互作用.
- 识别与不同类型的非综合症口腔裂相关的遗传变异.
- 探索性别作为对NSOFCs遗传敏感性的改变因素的作用.
主要方法:
- 一项涉及四组720名参与者的病例控制研究:NSCLP,NSCLO,NSCPO和健康对照,男性/女性比例为1:1.
- 使用实时PCR对两个单核酸多态 (SNP) 的基因定型:WNT3 rs3809857和NOG rs227731.
- 包括Bonferroni校正在内的统计分析和在衰退和主导遗传模型下的评估.
主要成果:
- 在一个衰退模型下,WNT3 rs3809857对男性的NSCLO具有显著的保护作用 (OR=0. 18, p=0. 0033).
- 在主导模型下观察到WNT3rs3809857和男性NSCLP之间的中度保护性关联 (p<0. 05).
- 在女性NSOFC亚型中没有发现WNT3的显著关联,而NOG rs227731则表明女性NSCLO和NSCPO的风险增加很小.
结论:
- 特别是在男性中,WNT3 rs3809857的多态性在降低NSCLO风险方面起着至关重要的作用.
- 这些发现强调了性别作为非综合征性口腔裂的遗传易感性的一个重要影响因素.
- 为了全面了解NSOFC,需要对性别特异性遗传因素进行进一步的研究.

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.

X-linked Traits
55.2K
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.

Background and Environment Affect Phenotype
6.7K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

The Ratio of X Chromosome to Autosomes
8.7K
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

Dosage Compensation
6.3K
In animals, gender is determined by the number and type of sex chromosome. For example, human females have two X chromosomes, and males have one X and one Y chromosome, whereas C.elegans with one X chromosome is a male, and the one with two X chromosomes is a hermaphrodite.
In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with distinct numbers of X chromosomes will...

Cis-regulatory Sequences
10.1K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...
