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...
Pleiotropy01:33

Pleiotropy

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,...
Sex Linked Disorders01:43

Sex Linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
Cohesins02:20

Cohesins

Cohesin protein complexes are a molecular glue that holds two sister chromatids together. They play an important role both in mitosis and meiosis. In mitosis, all cohesin complexes present on the chromosomes are removed before the start of the anaphase stage.
Cohesin complexes in Meiotic Division
Meiosis involves two distinct rounds of chromosomal segregation and cell divisions— Meiosis I followed by Meiosis II – producing four daughter cells. Meiosis I includes the separation of homologous...

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,...

Summary
This summary is machine-generated.

Shwachman-Diamond syndrome (SDS) is a rare genetic disorder causing pancreatic insufficiency, bone marrow failure, and skeletal issues. Severe bone abnormalities in SDS patients may require surgical correction, but neutropenia poses infection risks, complicating treatments.

Area of Science:

  • Genetics
  • Pediatrics
  • Orthopedics

Background:

  • Shwachman-Diamond syndrome (SDS) is a rare autosomal recessive disorder.
  • It is characterized by exocrine pancreatic insufficiency, bone marrow failure, and skeletal abnormalities.
  • Neutropenia affects 88-100% of patients, increasing infection susceptibility.

Observation:

  • Patients often exhibit failure to thrive, short stature, and increased susceptibility to infections.
  • Skeletal abnormalities include delayed ossification, metaphyseal irregularities, and osteopenia.
  • A clinical case highlights severe bone abnormalities managed with corrective osteotomy.

Findings:

  • The genetic basis of SDS was identified in 2002.
  • Bone abnormalities in SDS are progressive and vary with age and sex.
  • Persistent neutropenia is a significant risk factor for surgical interventions in SDS patients.

Implications:

  • Surgical correction of severe bone abnormalities in SDS is feasible but requires careful management of neutropenia.
  • The risk of infection due to neutropenia may contraindicate elective procedures like limb lengthening.
  • Further research is needed to optimize management strategies for skeletal complications in SDS.
