Genetic protein polymorphisms in human saliva: an interpretive review
Biochemical Genetics
|February 1, 1978
Summary
This review details genetic protein polymorphisms in human saliva, focusing on proline-rich (Pr), double-band (Db), acidic protein (Pa), and salivary peroxidase (SAPX) systems. These systems exhibit complex interrelationships and distinct genetic patterns, aiding phenotype definition.
Area of Science:
- Human Genetics
- Biochemistry
- Molecular Biology
Background:
- Salivary protein polymorphism research has evolved significantly since 1972.
- Previous studies primarily focused on salivary amylase genetics.
- This review concentrates on more recently investigated genetic systems in human saliva.
Purpose of the Study:
- To summarize advancements in human salivary genetic protein polymorphisms since 1972.
- To elucidate the complex interrelationships among proline-rich (Pr), double-band (Db), acidic protein (Pa), and salivary peroxidase (SAPX) systems.
- To discuss the utility and constraints of various gel electrophoresis systems for phenotype definition.
Main Methods:
- Review of scientific literature published since 1972.
- Analysis of genetic patterns and phenotype associations within Pr, Db, Pa, and SAPX systems.
- Evaluation of electrophoretic properties and gel systems for protein characterization.
Main Results:
- The proline-rich (Pr), double-band (Db), and acidic protein (Pa) systems display distinct genetic patterns and show phenotypic associations, suggesting linkage.
- Evidence indicates potential interactions between the products of the acidic protein (Pa) and salivary peroxidase (SAPX) loci.
- Electrophoretic techniques allow for accurate phenotype definition across different gel systems.
Conclusions:
- The genetic systems of Pr, Db, Pa, and SAPX in human saliva are biochemically related and exhibit complex genetic interplays.
- Electrophoresis provides a robust method for defining phenotypes, with varying utility across different gel systems.
- Understanding these genetic polymorphisms is crucial for advancing human genetics and salivary diagnostics.

Comparing Copy Number Variations and SNPs
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Single Nucleotide Polymorphisms-SNPs
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
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.

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...
Pharmacogenomics: Identification of New Drug Targets
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
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.
