#613718
Table of Contents
A number sign (#) is used with this entry because autosomal recessive deafness-74 (DFNB74) is caused by homozygous mutation in the MSRB3 gene (613719) on chromosome 12q14.
Waryah et al. (2009) reported 3 consanguineous Pakistani families with prelingual bilateral profound deafness inherited in an autosomal recessive pattern.
By genomewide linkage analysis of 3 consanguineous Pakistani families with autosomal recessive profound deafness, Waryah et al. (2009) identified a locus, termed DFNB74, on chromosome 12q14.2-q15. Maximum 2-point lod scores of 5.6, 5.7, and 2.6 were found for markers D12S313, D12S83, and D12S75, respectively. Haplotype analysis identified a 5.35-cM (5.36-Mb) candidate interval between D12S329 and D12S313.
Ahmed et al. (2011) refined the genetic interval for DFNB74 and found a homozygous missense mutation in the MSRB3 gene (613719.0001) in affected members of 6 different consanguineous Pakistani families with autosomal recessive prelingual deafness, including the 3 families previously reported by Waryah et al. (2009). They also identified a homozygous nonsense mutation in the MSRB3 gene (613719.0002) in affected members of 2 consanguineous Pakistani families with autosomal recessive prelingual deafness.

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,
