摘要: Peutz-Jeghers syndrome (PJS) was recently mapped in a single report to the telomeric region of chromosome 19p (A. Hemminki et al., Nat. Genet., 15: 87-90, 1997). Our studies confirm this location and provide further localization PJS locus. In five families examined, there were no recombinants with marker D19S886. The multipoint log odds score at D19S886 is 7.52, we found evidence for genetic heterogeneity. We also that all carriers expressed phenotype noncarriers displayed sequellae, indicating complete penetrance sporadic cases.
