Summary
Familial carpal tunnel syndrome (CTS) can occur without systemic disease. This family shows an inherited pattern of CTS with earlier symptom onset in younger generations, suggesting anticipation.
Area of Science:
- Neurology
- Genetics
- Orthopedics
Background:
- Carpal tunnel syndrome (CTS) is a common condition, typically sporadic and idiopathic.
- Inherited CTS often indicates an underlying systemic disease.
- Understanding familial CTS is crucial for genetic counseling and management.
Observation:
- A 35-year-old woman presented with carpal tunnel syndrome.
- A detailed family history revealed multiple affected members across generations, including her daughter, sister, father, and paternal grandmother.
- The age of onset in this family ranged from 9 to 52 years.
Findings:
- The observed pattern suggests autosomal dominant inheritance of carpal tunnel syndrome.
- A notable finding is the apparent decrease in age of onset in successive generations, a phenomenon known as anticipation.
- This familial CTS presentation is not linked to a known systemic disease.
Implications:
- This case highlights the possibility of idiopathic familial carpal tunnel syndrome.
- The anticipation pattern warrants further investigation into potential genetic mechanisms.
- Identifying genetic factors in familial CTS can improve diagnostic and therapeutic strategies.
