Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Alternative RNA Splicing02:18

Alternative RNA Splicing

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...
Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Area of Science:

  • Genetics
  • Cell Biology
  • Medical Genetics

Background:

  • Bardet-Biedl syndrome (BBS) is a rare autosomal recessive ciliopathy.
  • Characterized by retinal dystrophy, obesity, polydactyly, renal dysfunction, learning difficulties, and hypogonadism.
  • Minor features aid diagnosis and management.

Purpose of the Study:

  • Provide an overview of Bardet-Biedl syndrome.
  • Discuss current understanding of cilia biology.
  • Outline a practical approach to diagnosis, genetic counseling, and management.

Main Methods:

  • Diagnosis based on clinical findings.
  • Genetic confirmation through sequencing of known BBS genes in 80% of patients.
  • Review of BBS gene functions in cilia biogenesis and function.

Main Results:

  • BBS genes encode proteins essential for cilia and basal body function.
  • Mutations in BBS genes lead to defective cilia.
  • Defective cilia contribute to the pleiotropic effects observed in BBS.

Conclusions:

  • Understanding cilia biology is key to BBS pathogenesis.
  • A combined approach of clinical evaluation and genetic testing is vital for diagnosis.
  • Comprehensive management strategies are essential for patients with BBS.
