The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.9K
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,...

Pleiotropy01:33

Pleiotropy

43.7K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Epistasis01:39

Epistasis

50.7K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...

    Summary

    Tuberous sclerosis, a genetic disorder, was observed in identical twin brothers. Both presented with characteristic skin lesions and progressive mental deterioration, highlighting the condition's impact.

    Area of Science:

    • Medical Genetics
    • Dermatology
    • Neurology

    Background:

    • Tuberous sclerosis is a rare genetic disorder affecting multiple organs.
    • It is characterized by the formation of benign tumors in various parts of the body.
    • Genetic mutations lead to uncontrolled cell growth.

    Observation:

    • Identical twin brothers, six years old, presented with tuberous sclerosis.
    • Both were born with a single placenta and a single amnion, suggesting potential shared environmental or developmental factors.
    • Clinical manifestations included adenoma sebaceum, shagreen patches, and ash leaf spots.

    Findings:

    • Progressive mental deterioration was noted in both twin brothers.
    • One twin exhibited a verrucous pigmented nevus on the left temple.

  • Recurrent localized motor seizures were also observed in one of the twins.
  • Implications:

    • This case highlights the variable expressivity of tuberous sclerosis, even in genetically identical individuals.
    • Early recognition of dermatological signs is crucial for timely diagnosis and management.
    • Understanding the genetic and developmental underpinnings can inform future therapeutic strategies.
