The decisive step is genetic confirmation (karyotype/chromosomal microarray) alongside the AAP-recommended health surveillance for associated medical conditions. A single feature in isolation is not diagnostic; a recognisable pattern warrants onward referral.\n\n## Red flags that warrant referral\n**Craniofacial and physical**\n- Up-slanting palpebral fissures, epicanthic folds, flat nasal bridge, brachycephaly\n- Brushfield spots, small low-set ears, protruding tongue with small oral cavity\n- Single transverse palmar crease, fifth-finger clinodactyly, sandal-gap toe\n- Short stature trajectory, short neck with redundant nuchal skin\n\n**Neurodevelopmental**\n- Marked generalised hypotonia from infancy; poor head control\n- Global developmental delay — delayed motor milestones, delayed expressive language\n- Feeding difficulties in infancy\n\n**Associated medical (screen actively)**\n- Congenital heart disease (≈40–50%) — auscultate, consider echocardiography\n- Hearing and vision deficits; hypothyroidism; duodenal atresia/GI anomalies; atlantoaxial instability symptoms\n\n## When to refer\nA recognisable phenotypic pattern with hypotonia and delay justifies referral for [genetic confirmation](/down-syndrome) without delay. Refer in parallel for cardiology, audiology, ophthalmology and thyroid screening per AAP health-supervision guidance, and initiate early intervention — [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) and developmental support — while confirmation is arranged. Do not defer therapy pending the karyotype.\n\n## The Pinnacle way\nPinnacle Blooms Network supports your pathway with structured, multi-domain developmental profiling. The clinician-administered [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) provides an objective baseline across domains and tracks progress once intervention begins — it complements your clinical judgment and is not a diagnostic test. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.\n\n## Trusted sources\nAligned with WHO ICD-11 (LD40.0), CDC \"Learn the Signs.
