What is the difference between SNP and a mutation ? Entering edit mode 2.3 years ago QAZ • 0 Dears, I really confused between SNP and mutation. SNP can occur more than 1% in each column. If the SNP occurs less than 1% then it is considered as a mutation. if in the same column two nucleotides have been changed in the same position and the percentage of their occurrence together is less than 1% then there are two mutations in the same position. Is these info correct ? Please I have searched a lot and didn't find enough answer. I am a computer science students I am not a biologist. Thank you SNP Mutation • 3.2k views ADD COMMENT • link updated 2.3 years ago by 4galaxy77 2.8k • written 2.3 years ago by QAZ • 0 5 Entering edit mode 2.3 years ago GiantSilverSoy ▴ 130 People typically use the word “mutation” for the variations in the genome that are very rare and have phenotypic consequences, whereas “polymorphism” is used to describe those differences that are more common. “Variant” is a more neutral term that simply recognizes genetic differences between individuals. Source: https://cjasn.asnjournals.org/content/15/2/268 ADD COMMENT • link 2.3 years ago by GiantSilverSoy ▴ 130 2 Entering edit mode 2.3 years ago GenoMax 135k SNP = single nucleotide polymorphism (LINK). Technically a SNP is a mutation since it has resulted in a change when compared to a reference in that individual. I guess you are referring to a requirement that the SNP be present in at least 1% of the population to be considered a mutation by some definitions (see link). ADD COMMENT • link 2.3 years ago by GenoMax 135k Entering edit mode So, you mean if the occurrence is less than 1% it is called SNP. If the occurrence is bigger than 1% it is called a mutation. Or the reverse ? Thanks a lot ADD REPLY • link 2.3 years ago by QAZ • 0 Entering edit mode A single change is called a SNP (and it is still a mutation). Some definitions seem to want it to be present at least in 1% of the individuals of a population to be considered significant. Note: This may only be relevant to SNP's present in human populations. ADD REPLY • link 2.3 years ago by GenoMax 135k Entering edit mode In this link they have a comparison but I got more confused. https://pediaa.com/what-is-the-difference-between-snp-and-mutation/#SNP Please if these two upcoming sentences are correct then tell me. SNPs occurs > 1% Mutations occurs < 1% ADD REPLY • link 2.3 years ago by QAZ • 0 2 Entering edit mode By the definition used in link you provided they are calling SNP's to be mutations that occur in >1% of the population. SNP (single nucleotide polymorphism) is a type of DNA variant defined by the detectable with a more than 1% frequency within a population. Therefore, it is the most common genetic variation among people. A mutation is a change in genetic material in classical genetics. There is no percentage or frequency associated with that definition. A SNP would be classified as a point mutation (LINK). ADD REPLY • link 2.3 years ago by GenoMax 135k 2 Entering edit mode 2.3 years ago Camelia ▴ 30 I can confirm. Mutation is usually used for a rare variant that can have a pathogenic significance. SNPs are with a higher frequency in the general population and since they're present in the healthy people they're most likely benign, or at least don't have a complete pathogenic impact (hence the various studies which still manage to show some implications of SNPs in disease - usually complex multifactorial ones). Variant is a general term that includes both SNPs and mutations. It means a nucleotide in a specific position which is different than the reference genome. Of note, when you read classical genetic books, you'll see that mutation is defined as a change in the genome - similar definition to variant. then the definition continues with the classification of mutations in benign, pathogenic. So this might be confusing when you start reading/studying these subjects. But for the sake of being clear especially in a medical environment, we prefer: variant = any nucleotide change different than the consensus reference genome; mutation = pathogenic variant; SNPs = variant with >1% allele frequency that can be benign or maybe can have some effect in a certain context (quick example https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2564574/) cheers! ADD COMMENT • link 2.3 years ago by Camelia ▴ 30 1 Entering edit mode 2.3 years ago grant.hovhannisyan ★ 2.5k Any SNP is a mutation, but not any mutation is a SNP (deletion, duplication, etc). There is a also a difference between SNP and point mutation (or variant) - the latter is called a SNP if its frequency is higher than 1% in a given population. ADD COMMENT • link 2.3 years ago by grant.hovhannisyan ★ 2.5k 1 Entering edit mode 2.3 years ago 4galaxy77 2.8k In my experience nobody in everyday life every delineates SNPs and mutations based on their frequency, esepcially on some arbitrary cutoff like 1%, which IMO is quite an unhelpful criteria. Is it based on a frequency in a given population? Across all populations? How do you calculate the frequency? Working backwards and trying to figure out whether something is low or high frequency based on whether someone calls it a SNP or a mutation isn't very helpful. For example, the abstract of the 1000 genomes paper refers to singletons as SNPs, even though they are only found in a single individual (i.e. they are as low a frequency as its possible to get). https://www.nature.com/articles/nature15393 IMO the difference in terminology is far more about context than frequency. As others have suggested, 'mutations' is a common term in e.g. cancer genetics or rare disease discovery when talking about rare, singly occuring pathogenic variants which might occur in the germline. SNPs is used more often in population genetic or genetic epidemiology studies when people are talking about SNP arrays or SNP discovery in a population cohort. Of course, these often overlap.

Simple and fast methods for the detection of target genes with single-nucleotide specificity could open up genetic research and diagnostics beyond laboratory settings. We recently reported a biosensor for the electronic detection of unamplified target genes using liquid-gated graphene field-effect transistors employing an RNA-guided catalytically deactivated CRISPR-associated protein 9 (Cas9) anchored to a graphene monolayer. Here, using unamplified genomic samples from patients and by measuring multiple types of electrical response, we show that the biosensors can discriminate within one hour between wild-type and homozygous mutant alleles differing by a single nucleotide. We also show that biosensors using a guide RNA–Cas9 orthologue complex targeting genes within the protospacer-adjacent motif discriminated between homozygous and heterozygous DNA samples from patients with sickle cell disease, and that the biosensors can also be used to rapidly screen for guide RNA–Cas9 complexes that maximize gene-targeting efficiency. Liquid-gated graphene field-effect transistors anchoring guide RNA–Cas9 complexes can be used to discriminate between single-point mutations in human genomic samples.
