Full Form of CNV
What is CNV?
Copy Number Variation (CNV) refers to a type of structural variation in the genome where large segments of DNA are deleted or duplicated, resulting in an abnormal number of copies of one or more genes. In India, CNV analysis is increasingly used in clinical genetics for diagnosing inherited disorders, neurodevelopmental conditions, and cancer. It is commonly detected through techniques like array comparative genomic hybridization (aCGH) and next-generation sequencing. Research institutions and diagnostic labs across India utilize CNV profiling to identify genetic markers for diseases such as thalassemia, spinal muscular atrophy, and various cancers. For students preparing for NEET PG, CSIR NET, or GATE in biotechnology, understanding CNV is essential as it appears in questions on genomic variation and disease association. The role of CNVs in personalized medicine is growing, with Indian genomic studies contributing to population-specific databases. Overall, CNV analysis helps bridge the gap between genotype and phenotype, enabling better risk assessment and targeted therapies.

Example
The genetic counselor explained that the child's developmental delay was caused by a rare CNV on chromosome 16, which is not commonly seen in Indian population studies.
CNV — frequently asked questions
What is the full form of CNV?
The full form of CNV is Copy Number Variation, a type of structural genomic variation where segments of DNA are deleted or duplicated.
