Cytogenetic location: 1q43-q44 Genomic coordinates (GRCh38) : 1:236,400,001-248,956,422
Bhatti et al. (2008) studied a 6-generation consanguineous Pakistani family ('pedigree 4053') in which all affected members had prelingual profound nonsyndromic hearing impairment (NSHI) and used sign language for communication. There was no apparent vestibular involvement.
Bhatti et al. (2008) performed a whole genome scan in 4 affected and 6 unaffected members of a 6-generation Pakistani family segregating autosomal recessive NSHI and obtained a maximum multipoint lod score of 5.2 at marker D1S404. A region of homozygosity in affected individuals mapped the locus to a 5.1-Mb interval on chromosome 1q43-q44 between markers D1S1547 and D1S2836. The authors noted that this region overlaps with 2.7 Mb of the autosomal dominant NSHI locus DFNA34 (617772), which is located between markers D1S102 and D1S3739.
Exclusion Studies
In a 6-generation consanguineous Pakistani family with nonsyndromic hearing impairment mapping to a region containing 15 known genes on chromosome 1q43-q44, Bhatti et al. (2008) sequenced the promoters and exons of 3 candidate genes, CHML (118825), OPN3 (606695) and MAP1LC3C (609605), but found no potentially functional variants.

Dear OMIM User,
To ensure long-term funding for the OMIM project, we have diversified our revenue stream. We are determined to keep this website freely accessible. Unfortunately, it is not free to produce. Expert curators review the literature and organize it to facilitate your work. Over 90% of the OMIM's operating expenses go to salary support for MD and PhD science writers and biocurators. Please join your colleagues by making a donation now and again in the future. Donations are an important component of our efforts to ensure long-term funding to provide you the information that you need at your fingertips.
Thank you in advance for your generous support,
