Insights

Genetic disorders in South Africa's Indian population include rare heritable conditions, influenced by founder effects and endogamy. Thalassaemia is the most prevalent, requiring awareness for effective medical care.

Area of Science:

  • Medical Genetics
  • Population Genetics
  • South African Indian Community Health

Background:

  • Genetic disorders present unique challenges in diverse populations.
  • Understanding the genetic landscape of specific ethnic groups is crucial for public health.
  • The Indian population in South Africa has a distinct demographic and historical background.

Purpose of the Study:

  • To identify the spectrum of genetic disorders within South Africa's Indian population.
  • To analyze historical and demographic factors contributing to these genetic conditions.
  • To discuss the implications for genetic screening, diagnosis, and management.

Main Methods:

  • Retrospective review of patient data from paediatric practices and outreach clinics over 45 years.
  • Analysis of case details from special institutions for the handicapped.
  • Inclusion of data from the Cape Genetic Heritage archive.

Main Results:

  • Beyond common genetic disorders, several rare heritable conditions are prevalent.
  • The founder effect and the biological heritage of early immigrants shape the genetic profile.
  • Endogamy and other demographic factors are significant.
  • Thalassaemia is identified as the most common and critical genetic disorder in this population.

Conclusions:

  • Recognizing specific genetic disorders in the Indian community is vital for accurate diagnosis.
  • Precise diagnosis leads to better prognostication and optimized medical and genetic management.
  • This knowledge aids in developing targeted healthcare strategies for genetic conditions.

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...
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.

Principles of Pharmacogenetics: Types of Genetic Variants

The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...
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.
Human Genetics01:28

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...
