Abstract In late 2019, an outbreak of respiratory disease named COVID-19 started in the world. To date, thousands of cases of infection are reported worldwide. Most researchers focused on epidemiology and clinical features of COVID-19, and a small part of studies was performed to evaluate the genetic characteristics of this virus. Regarding the high price and low availability of sequencing techniques in developing countries, here we describe a rapid and inexpensive method for the detection of D614G mutation in SARS-CoV-2. Using bioinformatics databases and software, we designed the PCR-RFLP method for D614G mutation detection. We evaluated 144 SARS-CoV-2 positive samples isolated in six months in Northeastern Iran. Our results showed that the prevalent type is S-D in our isolates, and a small number of isolated belongs to the S-G type. Of 144 samples, 127 (88.2%) samples have belonged to type S-D, and 13 (9%) samples typed S-G. The first S-G type was detected on 2020 June 10. We have little information about the prevalence of D614G mutation, and it seems that the reason is the lack of cheap and fast methods. We hope that this method will provide more information on the prevalence and epidemiology of D614G mutations worldwide.

Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
