Living with Lethal recessive chondrodysplasia
An extremely rare inherited bone and cartilage condition with very short limbs and a narrow chest, noticed in newborns.
Understanding Lethal recessive chondrodysplasia
It involves severely shortened, curved limbs with normal hands and feet. The head is relatively large, the neck is short, and the chest is narrow. Muscles are floppy and joints are very loose. GARD notes no further descriptions in medical papers since 1988.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Shorter than typical limbs (micromelia)
- Narrow chest
- Breathing difficulties
- Small lower jaw (micrognathia)
- Large tongue (macroglossia)
- Dense bones (osteosclerosis)
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
Diagnosis
- 1Talk with your doctor
Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
- 2See a specialist
Specialists who may be involved include bone and joint specialists and genetic specialists.
- 3Ask which tests can help
Your care team will decide which exams and tests can confirm the diagnosis.
