The family history of uncomplicated congenital hydrocephalus: an epidemiological study based on 270 probands

Insights

Congenital hydrocephalus and neural tube defects may share common causes in families. This longitudinal study suggests a potential link between these conditions, with some exceptions noted.

Area of Science:

  • Pediatric Neurology
  • Medical Genetics
  • Developmental Biology

Background:

  • Congenital hydrocephalus and neural tube defects are significant birth defects.
  • Understanding the etiology of these conditions is crucial for prevention and treatment.
  • Family history studies provide insights into genetic and environmental factors.

Purpose of the Study:

  • To investigate the familial occurrence of congenital hydrocephalus and neural tube defects.
  • To explore potential shared etiological factors between these two conditions.
  • To analyze sibling recurrence risks for congenital hydrocephalus and neural tube defects.

Main Methods:

  • Longitudinal study design.
  • Inclusion of 270 babies with uncomplicated congenital hydrocephalus.
  • Analysis of family history data, including 453 siblings.
  • Comparison with previously published reports.

Main Results:

  • Five siblings (11.1/1000) of affected babies had congenital hydrocephalus.
  • Nine siblings (19.9/1000) of affected babies had neural tube defects.
  • Data suggest a common etiology for both conditions in many cases, with exceptions.

Conclusions:

  • Congenital hydrocephalus and neural tube defects likely share common etiological pathways.
  • Familial aggregation indicates a potential genetic component.
  • Further research is warranted to elucidate specific genetic and environmental influences.

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
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,...
