Novel autosomal recessive non-syndromic hearing impairment locus (DFNB71) maps to chromosome 8p22-21.3

J Hum Genet. 2009 Mar;54(3):141-4. doi: 10.1038/jhg.2009.2. Epub 2009 Feb 20.


A novel ARNSHI (autosomal recessive non-syndromic hearing impairment) locus, DFNB71, was localized to 8p22-21.3. To map the locus, a whole-genome scan was carried out using DNA samples from a consanguineous seven-generational Pakistani family with profound prelingual ARNSHI. A maximum multipoint LOD score of 4.2 occurred at marker D8S261. The DFNB71 region of homozygosity and 3-unit support interval is flanked by markers D8S1130 and D8S1786. This region has a genetic distance of 19.1 cM and contains 10.6 Mb of sequence.
