The Retinoblastoma Gene

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Incomplete Dominance

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Nondisjunction

Nondisjunction

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...

Nondisjunction

Nondisjunction

During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.

Sex-linked Disorders

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.

Summary

This summary is machine-generated.

Acquired Gerbode defects, abnormal left ventricle to right atrium shunts, can arise from infective endocarditis or valve surgery. Early echocardiogram assessment is crucial for timely diagnosis and management of these rare cardiac complications.

Background:

The Gerbode defect is a rare abnormal communication between the left ventricle and right atrium.
These defects can be congenital or acquired, with acquired cases often resulting from iatrogenic causes or infections.

Observation:

Two cases of acquired Gerbode defects are presented with similar clinical presentations but divergent outcomes.
Case 1: A 64-year-old male with decompensated cardiac failure and fever, diagnosed with infective endocarditis and a Gerbode defect secondary to bioprosthetic aortic valve dehiscence. Case 2: An 81-year-old male presenting with sepsis and heart failure, later found to have a complex aortic root lesion with valve dehiscence and a Gerbode defect.

Findings:

Infective endocarditis and bioprosthetic aortic valve dehiscence were identified as causes of the Gerbode defect in both patients.
Patient 1 underwent successful surgical repair and antibiotic treatment. Patient 2, despite treatment, succumbed to the infection and cardiac complications.

Implications:

The Gerbode defect is a significant complication associated with infective endocarditis and cardiac valve surgery.
Echocardiography plays a vital role in detecting Gerbode defect shunts, particularly in patients with a history of cardiac surgery.
Prompt diagnosis and management are critical for improving patient outcomes in cases of acquired Gerbode defects.
