A locus for complicated hereditary spastic paraplegia maps to chromosome 1q24-q32

We updated the clinical features of a consanguineous Arab Israeli family, in which four of seven children were affected by spastic paraplegia complicated by skin pigmentary abnormalities. A genomewide linkage screen performed for the family identified a new locus (SPG23) for this form of hereditary spastic paraplegia, in an approximately 25cM region of chromosome 1q24‐q32, with a peak logarithm of odds score of 3.05.
