概括
与对照组相比,有46,XX丸性别发育差异 (46,XX T-DSD) 的男性显示工作记忆得分较低. 虽然整体智力保持在正常范围内,但46,XX T-DSD男性的更高百分比得分处于低平均范围.
科学领域:
- 内分泌学 在内分泌学.
- 遗传学 是一个遗传学.
- 神经科学是一个神经科学.
背景情况:
- 46,XX丸性发育差异 (T-DSD) 是一种罕见的疾病,46XX染色体的个体具有男性表型.
- 以前的报道表明神经认知功能正常,但一些研究表明潜在的挑战,如教育程度较低.
研究的目的:
- 为了评估男性46,XX T-DSD的神经认知功能.
- 为了比较神经认知表现与46,XY男性对照,使用Wechsler成人智力量表,第四版 (WAIS-IV).
主要方法:
- 包括47名参与者:25名男性有46,XX T-DSD,22名匹配46,XY男性对照.
- 所有参与者都完成了WAIS-IV,评估了全尺度智商系数 (FSIQ) 和四个指数得分.
- 在大多数46,XX T-DSD病例中,遗传分析揭示了SRY转位,少数病例中发现了其他遗传原因.
主要成果:
- 与对照组相比,患有46,XX T-DSD的男性在工作记忆指数 (p=0.017) 上得分明显较低.
- 在46,XX T-DSD组中,口头理解指数和FSIQ的平均得分在数值上较低,但没有达到统计学意义.
- 在46,XX T-DSD男性中,56%的FSIQ得分处于低平均范围或以下,而对照组为13.6%.
结论:
- 与46,XY男性相比,46,XX T-DSD男性的工作记忆功能明显较低.
- 在认知指数得分中没有发现其他统计学上显著的差异,所有平均得分都在正常范围内.
- 需要进一步研究更大的队列和全面的非认知评估,以了解临床意义.

The Y Chromosome Determines Maleness
7.8K
The Y chromosome is a sex chromosome found in several vertebrates and mammals, including humans. In addition to 22 pairs of autosomes, the human males have one X chromosome and one Y chromosome. In these organisms, the presence or absence of the Y chromosome determines the development of male traits.
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size....

X and Y Chromosomes
29.3K
Among mammals, the gender of an organism is determined by the sex chromosomes. Humans have two sex chromosomes, X and Y. Every human diploid cell has 22 pairs of autosomes and one pair of sex chromosomes. A human female has two X chromosomes, while a male has one X chromosome and one Y chromosome.
The germline cells such as egg and sperm cells carry only half the number of chromosomes, i.e., 22 autosomes and one sex chromosome. All eggs have an X chromosome, while sperm cells can carry an X or...

Sex-linked Disorders
108.2K
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
58.2K
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”.

Development of the Sexual Organs in the Embryo and Fetus
3.2K
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the...

Testosterone: Functions and Regulation
2.0K
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
