It is the most common chromosomal abnormality and a leading cause of intellectual disability and developmental delay in children 👶. The risk increases with maternal age ⏳, often due to meiotic nondisjunction. Classic clinical features include flat facial profile, upslanting palpebral fissures, epicanthal folds, Brushfield spots in the iris, and a single transverse palmar crease ✋. Associated anomalies include congenital heart defects (especially AV canal defects) ❤️, duodenal atresia, hypothyroidism, hearing loss, and an increased risk of leukemia (especially ALL & AML). Early intervention, cardiac screening, and supportive therapies are essential for better quality of life. Karyotyping confirms the diagnosis, with 95% due to free trisomy, 4% Robertsonian translocation, and 1% mosaicism. Understanding the mechanisms and phenotypic spectrum is crucial for medical students preparing for NEET PG, FMGE, or USMLE. 👩‍⚕️👨‍⚕️ #DownSyndrome #Trisomy21 #GeneticsMadeEasy #NEETPG #USMLEPrep #FMGE #PaediatricsRevision #ChromosomalDisorders #MedicalEducation #MBBSLife #HighYieldTopics #BrushfieldSpots #DevelopmentalDelay #ConceptualMedicine #CongenitalSyndromes #ClinicalFeatures
