At the center of this shift are the 2015 standards from the American College of Medical Genetics & Genomics (ACMG), which established a structured framework for interpreting sequence variants. ๐น Genetic variants influence disease risk, diagnosis, prognosis, & therapeutic strategy. Without standardized interpretation, clinical decisions become inconsistent. The ACMG/AMP framework addresses this by integrating multiple evidence streams into five categories: 1. Pathogenic (Class 5) 2. Likely Pathogenic (Class 4) 3. Variant of Uncertain Significance [VUS] (Class 3) 4. Likely Benign (Class 2) 5. Benign (Class 1) This tiered system reduces interpretive subjectivity & improves reproducibility...

They arise through mechanisms like unequal crossing over, retroposition, or whole-genome duplication (WGD). Once a gene is duplicated, one copy can conserve its original role, while the other diverges; fueling new functions, adaptations, or even nonfunctionalization (pseudogenes). ๐น The evolutionary fates of gene duplications includes: Subfunctionalization: split ancestral functions across duplicates. Neofunctionalization: gain of new roles, which is vital for innovation. Pseudogenization: loss of function. A classic case is the globin gene family: duplications enabled the evolution of h...
