Fig. 1. Identification of NTRK1 mutation.
a The pedigree of family 6807. b Linkage analysis plot for family 6807. c Microsatellite markers for chromosome 1, including NTRK1 region. Haplotypes for. available members of the family (orange indicates 2nd generation, green indicates 3rd generation) and inferred haplotype for 1st generation father. Yellow columns indicate regions of homozygosity and blue regions indicate recombination events.
