- Description
- Alterations in the DNA sequence are generally seen in the general population at >1%, and these alterations can be deletions or insertions. Classically, chromosomal polymorphisms (CPMs) are alterations with no significant phenotypic distinctions. However, few studies have shown that the presence of CPM can lead to congenital disabilities, which can be fatal. These variants in the DNA can happen in the form of single nucleotide polymorphisms (SNPs). The human genome is considered full of SNPs, and they are responsible for causing pathological phenotypes and provide insight into pathogenesis, a therapeutic approach to the pathology. About 100 million SNPs are observed in humans for an average of 300 nucleotides. These polymorphisms are detected by using molecular techniques. These polymorphisms are not just restricted to the coding region. The CPMs are first recognized on the chromosomes through molecular techniques, followed by detection of the polymorphism. The CMPs are generally the SNPs, deletions/duplications, and presence of microsatellite DNAs. Here we have summarized the implications of CMPs in a few congenital disorders and the method of diagnosis. The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.
