Ei. Rogaev et al., MAPPING OF THE GENE FOR DOMINANT PALMOPLA NTARIS HYPERKERATOSIS (TYLOSIS) ON CHROMOSOME 17Q12-Q24, Genetika, 30(3), 1994, pp. 326-329
Mapping of the genetic defect causing dominant palmoplantaris hyperker
atosis (PPHK) was continued based on the material of an extended Uzbek
pedigree. No linkage between the PPHK gene and hypervariable DNA mark
ers from 8p, 12p, 14q, and 22q were revealed. The study of PPHK gene t
o 17q12-q24 and revealed close linkage with KRT10 and D17S800 loci (ze
ro recombination frequency at a lod score > 7). The possible location
of a PPHK mutation in one of the keratin genes mapped to the same regi
on on the 17th chromosome is discussed.
