Carpal tunnel syndrome is common in adults and is usually sporadic and
idiopathic. When carpal tunnel syndrome is inherited, it is often the
manifestation of a systemic disease. We report carpal tunnel syn drom
e in an otherwise healthy woman aged 35 years. Family history reveals
that her daughter, her sister and a sister's daughter, an aunt,. first
cousin, her father and the paternal grandmother are also affected. Th
e age of onset of the disease in this family was between 9 and 52 year
s of age. The family in this paper demonstrates an interesting pattern
of inheritance with earlier onset of symptoms in subsequent generatio
ns, suggestive of anticipation.
