- 瘤学和癌症管理
背景情况:
- 生殖系CDH1致病或可能致病 (P/LP) 变体与遗传性扩散性胃和叶状乳腺癌综合征有关.
- 患有CDH1变异的个体的生殖决策尚未得到充分研究,特别是在计划生育方面.
- 遗传性癌症综合征的诊断显著影响生殖年龄的个体的生殖选择.
研究的目的:

主要成果:
- 50%的个人报告说他们的CDH1诊断影响了计划生育决策.
- 47%遇到生殖的心理或经济障碍;12%因为癌症风险管理而延迟怀孕.
- 妇女经历过传递CDH1变异的内感; 怀孕后PTG有成功的胎儿结果,但潜在的母性微量营养素缺乏和恶化的胃切除术后综合征.
结论:
- 对于CDH1变异的个体来说,生殖决策是复杂的,涉及心理社会和身体挑战.

Genomic Imprinting and Inheritance
35.3K
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...

Nondisjunction
4.1K
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...

The Ratio of X Chromosome to Autosomes
8.8K
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...
