Insights

Congenital heart malformations, the most common birth defects, often stem from genetic causes. This review explores the genetic factors, including inheritance patterns and specific genes, contributing to these conditions.

Area of Science:

  • Genetics
  • Developmental Biology
  • Pediatrics

Context:

  • Congenital heart malformations (CHMs) are prevalent, affecting 0.5-1% of newborns.
  • CHMs represent the most common category of birth defects.
  • Genetic factors are increasingly recognized as significant contributors to CHMs.

Purpose:

  • To review the current understanding of the genetic basis of congenital heart disease.
  • To explore various modes of genetic inheritance implicated in CHMs.
  • To highlight identified genes associated with congenital heart defects.

Summary:

  • CHMs can arise from autosomal dominant, autosomal recessive, and X-linked inheritance patterns.
  • Mitochondrial inheritance and chromosomal abnormalities are also identified causes of CHMs.
  • Numerous specific genes linked to congenital heart defects have been discovered.

Impact:

  • Provides a comprehensive overview of genetic etiologies for CHMs.
  • Aids researchers in identifying novel genetic targets for CHM.
  • Informs clinical geneticists and pediatricians on the genetic landscape of congenital heart disease.

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
Incomplete Dominance01:43

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Cardiomyopathy I: Introduction and Classification

Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...
Cardiomyopathy II: Dilated Cardiomyopathy01:30

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
