4q12-q13.2 | Deafness, autosomal recessive 55 | 609952 | AR | 2 |
Irshad et al. (2005) reported a consanguineous Pakistani family with nonsyndromic deafness segregating as an autosomal recessive trait. Affected members of the family had prelingual profound deafness involving all frequencies.
By linkage analysis, Irshad et al. (2005) mapped the nonsyndromic deafness phenotype in a consanguineous Pakistani family to chromosome 4q12-q13.2. A maximum multipoint lod score of 3.5 was obtained at marker D4S2638, and an 8.2-cM (11.5-Mb) region of homozygosity was flanked by markers D4S2978 and D4S2367. Irshad et al. (2005) noted that this locus is within the genetic interval for the DFNA27 locus (612431), which maps between D4S428 and D4S392. By sequence analysis, Irshad et al. (2005) detected no functional mutations in the candidate genes EPHA5 (600004) or REST (600571).

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,
