Physical map of the region surrounding the OTOFERLIN locus on chromosome 2p22-p23

The autosomal recessive form of nonsyndromic deafness DFNB9 has been mapped to a 2-cM, region on chromosome 2p22-p23, and the responsible gene, OTOF, has been recently identified by positional cloning combined with a candidate gene approach. In the course of this gene cloning, we established a contig of yeast artificial chromosomes, bacterial artificial chromosomes, and P1 phage artificial chromosomes delimited by polymorphic markers D2S2170 and D2S170, i.e., extending over approximately 3500 kb. Sixty expressed sequence tags or genes and 14 sequence-tagged sites, 11 of which are polymorphic, were mapped to this contig and assigned to 21 chromosomal intervals. (C) 2000 Academic Press.
