Summary
This study identifies a novel mutation in the retinal degeneration slow (RDS)/peripherin gene associated with pattern dystrophy of the retina. This finding advances understanding of the genetic basis of this vision-impairing condition.
Area of Science:
- Ophthalmology
- Genetics
- Molecular Biology
Background:
- Pattern dystrophy of the retina is a group of inherited retinal diseases.
- The genetic underpinnings of many retinal dystrophies remain incompletely understood.
- Retinal degeneration slow (RDS)/peripherin gene mutations are implicated in various retinal disorders.
Purpose of the Study:
- To report a case of pattern dystrophy of the retina.
- To conduct genetic analysis to identify the molecular cause of the disease.
- To describe a novel mutation within the RDS/peripherin gene.
Main Methods:
- Clinical examination of a patient with bilateral pattern dystrophy.
- Detailed ophthalmological assessment including visual acuity and funduscopy.
- Molecular genetic testing of the RDS/peripherin gene.
Main Results:
- A 46-year-old male presented with a 6-year history of vision loss.
- Bilateral pattern dystrophy of the retina was diagnosed, with predominant involvement of the right eye.
- A novel mutation, G665C (C222S), was identified in the RDS/peripherin gene.
Conclusions:
- The identified RDS/peripherin mutation is associated with pattern dystrophy of the retina.
- This represents the first reported instance of this specific mutation.
- This discovery contributes to the genetic landscape of retinal pattern dystrophies.

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,...

Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

Alternative RNA Splicing
27.6K
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

Exon Recombination
4.4K
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.
Exon shuffling follows “splice frame rules.” Each exon...

Incomplete Dominance
32.9K
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.
