Updated genetic mapping data and deduced haplotypes for the CMT1019 family. Additional genetic mapping data was collected for key members of the CMT1019 family originally reported by Ionasescu et al. (1996). The indicated order of the genetic markers from 7pter (top) to 7cen (bottom) was established by YAC-based physical mapping (Bouffard et al. 1997b). Note that individual 60 is indicated as unaffected (unlike the original description of this family, where this individual was coded as affected) and individual 40 is represented by a hatched symbol to indicate an uncertain phenotypic status (see text). (Solid bars) Affected haplotype; (open bars) a normal chromosome. Also note the recombination events detected in individual 40 (denoted by a switch from an open to a solid bar at D7S1808) and individual 26 (denoted by a switch from an open to a solid bar at D7S632).
