Living with Nonsyndromic congenital nail disorder 1
A genetic condition affecting the fingernails and toenails, with thick nails that lift away from the nail bed and look claw-like.
Understanding Nonsyndromic congenital nail disorder 1
Nails are extremely thick (onychauxis), may lift off the nail bed (onycholysis), and can look claw-like. Some fingers and toes may be missing part of the nail. Nails are often abnormal from birth but may not be noticed until later in childhood because they grow slowly. GARD says people have no other health problems related to the condition.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Poorly formed fingernails (nail dysplasia)
- Brittle nails
- Grooved or ridged nails
- Nail pits
- Spoon-shaped nails
- Thin nails
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
