Achondroplasia is the most common skeletal dysplasia, caused mainly by a recurring gain‑of‑function FGFR3 mutation that impairs endochondral bone growth. It produces disproportionate short stature with characteristic clinical and radiographic features allowing reliable diagnosis; genetic testing can confirm unclear or prenatal cases. Management varies worldwide, so an international panel of 55 experts produced 160 consensus statements covering diagnosis, genetics, prenatal counselling, pregnancy care, and multidisciplinary lifelong management. Key priorities include early referral to specialized teams, routine monitoring in infancy for foramen magnum stenosis, screening and treatment of sleep‑disordered breathing and ear disease, growth and developmental surveillance using achondroplasia‑specific charts, proactive prevention and management of obesity, and timely surgical referral for spinal or limb complications. Psychosocial support, transition planning, and equitable access to specialized care are emphasized. New precision therapies are emerging but do not replace comprehensive multidisciplinary care.
Key Take Aways:
This article will provide valuable insights into:
- Cause and diagnosis: Achondroplasia is mostly due to a common FGFR3 mutation; clinical/radiographic signs usually suffice but genetic testing helps in atypical or prenatal cases.
- Early infant surveillance: Regular specialist follow-up (including MRI and sleep studies) is critical to detect foramen magnum stenosis and sleep‑disordered breathing that can be life‑threatening.
- Lifelong multidisciplinary care: Routine monitoring (growth, hearing, spine, ENT, nutrition, psychosocial) by experienced teams improves outcomes across life stages.
- Surgical and specialty referrals: Neurosurgical, spinal, ENT, orthopaedic, and anaesthesia care should involve clinicians experienced with achondroplasia; limb lengthening and major surgeries require multidisciplinary evaluation.
- Psychosocial and access issues: Families need counselling, advocacy group links, transition planning, and equitable access to specialized services; new drug therapies will complement but not replace holistic care.
