Monogenic hearing loss v4.14 | GOSR2 |
Achchuthan Shanmugasundram gene: GOSR2 was added gene: GOSR2 was added to Monogenic hearing loss. Sources: Literature Mode of inheritance for gene: GOSR2 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: GOSR2 were set to 37074134 Phenotypes for gene: GOSR2 were set to hearing loss, autosomal recessive, MONDO:0019588 Review for gene: GOSR2 was set to RED Added comment: Four children from two sibships from an extended consanguineous Palestinian family were reported with congenital profound hearing loss, whereas the parents of both sibships are first cousins with normal hearing. The families reported occasional febrile seizures in infancy for each of the deaf children, but these did not persist into adolescence. These affected children were identified with autosomal recessive GOSR2 variant, c.1A > C, p.Met1Leu. This variant appeared once in the gnomAD database, as a heterozygote, and not in any of ~2000 in-house controls of Palestinian ancestry. All previously reported cases with biallelic GOSR2 variants had normal hearing and hence the differences in translation efficiency due to the effect of this variant may be responsible for this hearing loss phenotype (PMID:37074134).

Monogenic hearing loss v2.168 | CRYM |
Eleanor Williams edited their review of gene: CRYM: Added comment: Associated with Deafness, autosomal dominant 40 #616357 (AD) in OMIM. PMID: 32742378 - Wang et al 2020 - report a 4 generation Chinese family with 31 members, of which 7 have hearing loss. WES identified a heterozygous missense mutation in CRYM (c.152C>T; Pro51Leu) which segregated with the phenotype in the family. As Zornitza Stark reports gnomad (3.1.1) has 2 hets reported (allele freq of 1.32e-5). PMID: 12471561 - Abe et al 2003 - used genome-wide cDNA microarray analysis to investigate gene-expression profiles in human cochlea and vestibule and identified CRYM as a candidate gene. They then screened CRYM, among 192 patients with nonsyndromic deafness. Two unrelated Japanese patients were identified with variants in CRYM; one with a de novo change (c.945A→T, p.X315Y) which results in an extended protein in a patient with unaffected parents, and the other was a missense mutation (c.941A→C;p.K314T) that segregated dominantly in the proband’s family. PMID: 16740909 - Oshima et al 2006 - looked at the effect of the two variants found by Abe et al, X315Y and K314T by looking at T3 binding activity of the mutant μ‐crystallin (product of CRYM) proteins. They found the K314T mutation impaired the NADPH dependent T3 binding (but did not find this for the X315Y variant). They also showed that μ‐crystallin protein localisation in mouse cochlea using immunocytochemical methods. PMID: 18448257 - Usami et al 2009 - showed that Crym protein localizes in type II fibrocytes of the spiral ligament in the cochlea in mice and rats PMID: 24676347 - Yoshimura et al 2014 - show a gradient of gene expression of CRYM in mouse cochlea PMID: 26915689 - Hosoya et al 2016 - immunohistochemical analysis of expression of CRYM in cochlea of a non-human primate, the common marmoset and found a different expression pattern compared to mouse, with expression not only in the lateral wall spiral ligament and the spiral limbus, but also in both inner and outer hair cells, supporting cells.; Changed publications to: 32742378, 12471561, 16740909, 18448257, 24676347, 26915689; Changed phenotypes to: Deafness, autosomal dominant 40, OMIM:616357, autosomal dominant nonsyndromic deafness 40, MONDO:0014603; Changed mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown |

They identified, through genome-wide homozygosity mapping and then whole exome sequencing, a homozygous missense variant located in MET (NM_000245.2), c.2521T>G (p.F841V) that segregates with hearing loss in 9 affected individuals. PMID: 27717089 - Alabdullatif et al 2017 - from a review of clinical and molecular data for 227 individuals from a highly consanguineous population who underwent a combined (CGH+SNP) CMA test, they report 2 brothers with hearing loss and arthrogryposis in which a homozygous variant c.3557T>G (p.F1186C) in MET was identified through WES after a region of homozygosity was identified. The first cousin parents were both heterozygous for this variant. They suggest that the arthrogryposis could be a variable feature of the disease or be caused by a second recessive disease not detected in this study. Sources: Expert list |
