Summary
Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) is linked to a 7q11.23 microduplication in a rare case. This finding suggests a potential new genetic cause for MRKHS.
Area of Science:
- Genetics
- Reproductive Medicine
Background:
- Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) involves congenital absence of the uterus and vagina in 46, XX females.
- The genetic basis of MRKHS is not well understood.
Observation:
- A 29-year-old female presented with primary amenorrhea.
- MRKHS was diagnosed, and genetic analysis revealed a 7q11.23 microduplication inherited from her mother.
Findings:
- This is the first reported case of co-occurring 7q11.23 microduplication syndrome and MRKHS.
- Müllerian malformations are rarely associated with 7q11.23 microduplication.
Implications:
- The 7q11.23 duplication may represent a novel candidate region for MRKHS.
- This case expands the known clinical spectrum of 7q11.23 microduplication syndrome.

Meiosis I
191.6K
Meiosis is a carefully orchestrated set of cell divisions, the goal of which—in humans—is to produce haploid sperm or eggs, each containing half the number of chromosomes present in somatic cells elsewhere in the body. Meiosis I is the first such division, and involves several key steps, among them: condensation of replicated chromosomes in diploid cells; the pairing of homologous chromosomes and their exchange of information; and finally, the separation of homologous chromosomes by...

Genomic Imprinting and Inheritance
32.8K
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...

Oogenesis
63.1K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Sex-linked Disorders

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.

Centrosome Duplication
3.8K
The primary microtubule organizing center (MTOC) in animal cells is the centrosome. A centrosome has two cylindrical centrioles at its core. Each centriole consists of nine sets of three microtubules held together by proteins. The centrioles are positioned at right angles to each other and surrounded by a shapeless protein cloud called the pericentriolar matrix, or pericentriolar material (PCM).
