Abstract

The neurotrophic tyrosine kinase receptor type 2 (NTRK2) gene is a member of the trk family of tyrosine protein kinases, which encode receptors for the nerve growth factor-related proteins known as neurotrophins. The neurotrophins and their receptors have long been considered candidate genes for familial dysautonomia (FD), a hereditary sensory neuropathy resulting from the congenital loss of both sensory and autonomic neurons. The DYS gene has recently been mapped to human chromosome 9q31-q33, and therefore we set out to determine the chromosomal localization of the candidate gene NTRK2. A mouse trkB probe was hybridized to both somatic cell hybrids containing human chromosome 9 and a human chromosome 9 flow-sorted cosmid library. The human homologue of trkB, NTRK2, was assigned to chromosome 9. To localize the NTRK2 gene further, a dinucleotide repeat polymorphism was identified within a cosmid that contains NTRK2 exon sequences. This marker was genotyped in the CEPH reference pedigrees and places the NTRK2 gene near D9S1 on the proximal long arm of human chromosome 9. The NTRK2 gene is located approximately 22 cm proximal to DYS and shows several recombinants in disease families. Therefore, the NTRK2 gene can now be excluded as a candidate gene for familial dysautonomia.
