X and Y Chromosomes02:32

X and Y Chromosomes

27.1K
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...

Meiosis I01:49

Meiosis I

196.6K
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...

The Ratio of X Chromosome to Autosomes02:45

The Ratio of X Chromosome to Autosomes

8.9K
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...

Polytene Chromosomes02:04

Polytene Chromosomes

10.3K
Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also...

Meiosis vs. Mitosis02:57

Meiosis vs. Mitosis

59.9K
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...

Area of Science:

  • Genetics
  • Cardiology
  • Endocrinology

Background:

  • Turner syndrome is a chromosomal condition affecting females, often associated with various health issues.
  • Ring X chromosome is a rare variant of Turner syndrome, with limited data on its specific clinical manifestations.
  • Congestive cardiac failure (CCF) and dilated cardiomyopathy (DCM) are known complications in Turner syndrome, but their association with ring X chromosome is exceptionally rare.

Observation:

  • A young female patient presented with symptoms of congestive cardiac failure, including anasarca, jaundice, and orthopnea.
  • She exhibited characteristic features of Turner syndrome such as growth retardation, intellectual disability, primary amenorrhea, and specific dysmorphic traits.
  • Echocardiography revealed dilated cardiomyopathy with an intracardiac thrombus, and skeletal surveys showed short metacarpals/tarsals.

Findings:

  • Karyotyping confirmed a mosaic pattern with 45,X/46,X,r(X)(p22.3q28), indicating Turner syndrome with a ring X chromosome.
  • The patient's presentation of DCM and heart failure was directly linked to this rare chromosomal abnormality.
  • Management involved vasopressors, anticoagulants for the thrombus, and hormone replacement therapy.

Implications:

  • This case underscores the association between ring X chromosome in Turner syndrome and the development of dilated cardiomyopathy.
  • It emphasizes the importance of comprehensive cardiac evaluation in patients with rare chromosomal abnormalities.
  • Highlights the need for tailored management strategies for complex cases of Turner syndrome involving cardiac complications.
