When the pattern is present, confirm by karyotype and start the cardiac, hearing and thyroid surveillance bundle with early intervention.","answer_md":"*The newborn examination is often where the first clinical pattern emerges — a constellation of subtle signs that, taken together, prompts the right conversation and the right test.*\n\n## In short\nDown syndrome (Trisomy 21, [ICD-11 LD40.0](/down-syndrome)) is recognisable at or near birth from a cluster of physical features and hypotonia rather than any single sign. When the pattern is present, arrange confirmatory karyotyping and a structured early-intervention pathway — most importantly cardiac, hearing and thyroid screening — without delay. No feature is diagnostic alone; chromosomal analysis confirms.\n\n## Early indicators to watch for\n**Neonatal / craniofacial**\n- Generalised hypotonia with reduced Moro and poor head control\n- Flat facial profile, flattened nasal bridge, upslanting palpebral fissures\n- Epicanthic folds and Brushfield spots on the iris\n- Small, low-set ears; protruding tongue with small oral cavity; flat occiput\n- Short neck with excess nuchal skin\n\n**Limbs and extremities**\n- Single transverse palmar (simian) crease\n- Brachydactyly; clinodactyly of the fifth finger\n- Wide sandal gap between first and second toes\n- Joint hyperflexibility\n\n**Functional / developmental**\n- Feeding difficulty and poor suck in the neonatal period\n- Subsequent delay across gross-motor, fine-motor and speech-language milestones\n\n## When to act\nWhere the gestalt is present, send peripheral-blood karyotype (or QF-PCR/FISH for rapid result) to confirm. In parallel, follow the standard surveillance bundle: echocardiography (≈40–50% have congenital heart disease, often AVSD), newborn hearing screen, TSH/thyroid function, red-reflex/ophthalmology review, and a feeding assessment. Counsel the family early and refer for [early intervention and speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) — developmental support from infancy meaningfully improves functional outcomes.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — the [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) is a clinician-administered structured assessment that gives a multi-domain developmental baseline to complement your examination and track progress once intervention begins. It supports your clinical judgment; it never replaces karyotype confirmation. Pinnacle's network spans 70+ centres across 4 states with 700+ therapists, supporting [Down syndrome](/down-syndrome) families through the early years.\n\n## Trusted sources\nAligned with WHO ICD-11 (LD40.0), CDC \"Learn the Signs. Act Early.\", the Indian Academy of Pediatrics, and the American Academy of Pediatrics (HealthyChildren.org).\n\n**Next step —** to refer a newborn or infant for structured developmental support,
