Abstract

The genetic etiology for many forms of hearing impairment (HI) is very diverse. Non-syndromic HI (NSHI) is one of the most heterogeneous traits known. Autosomal recessive forms of prelingual HI account for ∼75% of hereditary cases. A novel autosomal recessive NSHI locus, DFNB44, was mapped to a 20.9 cM genetic interval on chromosome 7p14.1-q11.22, according to the Marshfield genetic map, in a consanguineous Pakistani family. Multipoint linkage analysis resulted in a maximum LOD score of 5.0 at marker D7S1818. The 3-unit support interval ranged from marker D7S2209 to marker D7S2435, spanning a 30.1 Mb region on the sequence-based physical map.
