Summary
This study details Bannayan-Riley-Ruvalcaba syndrome in 12 family members, revealing overlaps with other genetic conditions and adding Hashimoto thyroiditis to its phenotype. The research also explores the syndrome's link to juvenile polyposis.
Area of Science:
- Genetics
- Pediatrics
- Endocrinology
Background:
- Bannayan-Riley-Ruvalcaba syndrome is a rare genetic disorder.
- Previous research suggested potential overlaps with other rare syndromes.
- The full spectrum of Bannayan-Riley-Ruvalcaba syndrome manifestations was not completely understood.
Observation:
- The study examined 12 individuals from a single family affected by Bannayan-Riley-Ruvalcaba syndrome.
- Clinical data revealed significant overlap with Bannayan-Zonana syndrome, Riley-Smith syndrome, and Ruvalcaba-Myhre syndrome.
- Hashimoto thyroiditis was identified in 7 of the affected family members.
Findings:
- Autosomal dominant inheritance pattern confirmed for Bannayan-Riley-Ruvalcaba syndrome.
- Clinical presentation demonstrates considerable phenotypic overlap with Bannayan-Zonana, Riley-Smith, and Ruvalcaba-Myhre syndromes.
- Hashimoto thyroiditis is a newly identified component of the Bannayan-Riley-Ruvalcaba syndrome phenotype.
Implications:
- This research refines the diagnostic criteria for Bannayan-Riley-Ruvalcaba syndrome.
- Understanding the phenotypic spectrum aids in early diagnosis and management.
- Further investigation into the genetic and molecular links between these overlapping syndromes is warranted.

Overview
01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

01:20The 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,...

01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
01:29Cardiomyopathy IV: Restrictive Cardiomyopathy
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
01:30Bulimia Nervosa
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...
