Description

A syndrome characterised by spastic paraplegia and pigmentary abnormalities.

Abdallat et al. in 1980 reported a Jordanian family in which 2 brothers and a sister from first-cousin parents had disordered skin and hair pigmentation, progressive spastic paraparesis and peripheral neuropathy. Sural nerve biopsy showed axonal degeneration; skin biopsy showed abnormal epidermal pigmentation. The proband had diffusely depigmented hair and skin at birth. From the age of 6 months, patchy pigmentation developed, especially in exposed areas of the skin, and his hair developed irregular pigmentation. Progressive paraparesis was first noted at age 6 years.
