Photoreceptors and Visual Pathways

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Translation

Translation

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.
Translation Produces the Building Blocks of...

Summary

This summary is machine-generated.

Persistent hyperferritinaemia without iron overload can indicate rare genetic conditions like hyperferritinaemia-cataract syndrome. Genetic testing is crucial for accurate diagnosis and avoiding unnecessary treatments.

Biochemistry
Genetics
Ophthalmology

Background:

Elevated serum ferritin is common, often linked to inflammation, liver disease, alcohol, or malignancy.
Rare genetic conditions can also cause hyperferritinaemia, necessitating broader diagnostic considerations.

Observation:

A male patient in his sixties presented with persistent hyperferritinaemia without iron overload.
He developed cataracts, prompting his own suggestion of hyperferritinaemia-cataract syndrome.

Findings:

Mutation analysis confirmed the patient's light chain ferritin (FTL) gene had mutations.
These FTL gene mutations are inherited in an autosomal dominant pattern.
FTL mutations disrupt the balance between iron levels and ferritin production.

Implications:

Considering rare genetic causes like FTL mutations is vital when common causes of hyperferritinaemia are ruled out.
Accurate genetic diagnosis can prevent unnecessary procedures and treatments.
Genetic testing for FTL mutations should be utilized by clinicians when indicated.
