Anne McLaren 🧬 Human gene variation databases are foundational to modern genomics, transforming raw sequencing data into actionable biological and clinical insight. As genomic technologies scale, these resources enable consistent interpretation of genetic diversity across populations, diseases, and evolutionary contexts.           🔹 At the core is dbSNP, a comprehensive catalogue of single nucleotide polymorphisms and small insertions/deletions curated by NCBI. By assigning standardized rsIDs, dbSNP ensures global consistency in variant reporting, supporting reproducibility across studies in population and disease genetics.          🔹 The 1000 Genomes Project provides a global reference of human genetic variation across diverse ancestries. It remains essential for understanding population st...

Two primary methods dominate: microarrays and RNA sequencing (RNA-seq). Both yield critical insights but differ in methodology, sensitivity, and applications.          🔹 An early high-throughput approach, microarrays use DNA probes on chips to detect labeled cDNA derived from RNA samples. Fluorescence intensity indicates gene activity. Microarrays excel in comparative studies with known gene sets and large cohorts but are limited by probe d...

Translational regulation allows cells to rapidly adapt to stress, developmental signals, or environmental changes, fine-tuning protein output without altering transcription.  🔹 Recruitment of ribosomes to mRNAs is tightly regulated by eukaryotic initiation factors (eIFs). For example, eIF2α phosphorylation globally reduces translation during stress, yet mRNAs with upstream open reading frames (uORFs) or internal ribosome entry sites (IRESs) can bypass this, ensuring selective protein production.  🔹 Elongation and termination are influenced by elonga...
