| Monogenic hearing loss v4.24 | PSMC3 | Achchuthan Shanmugasundram Added comment: Comment on mode of inheritance: There is sufficient evidence for the association of monoallelic variants from this gene with hearing loss. However, there is only one family reported with biallelic variants. Hence, the MOI is set as "MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted". | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Achchuthan Shanmugasundram gene: PSMC3 was added gene: PSMC3 was added to Monogenic hearing loss. Sources: Literature Mode of inheritance for gene: PSMC3 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: PSMC3 were set to 32500975; 37256937 Phenotypes for gene: PSMC3 were set to ?Deafness, cataract, impaired intellectual development, and polyneuropathy, OMIM:619354; neurodevelopmental disorder, MONDO:0700092; autosomal dominant nonsyndromic hearing loss, MONDO:0019587 Review for gene: PSMC3 was set to GREEN Added comment: PMID:32500975 - Three individuals from a single extended consanguineous Turkish pedigree was reported with early-onset and rapidly progressive deafness, early-onset cataract, severe developmental delay, severely impaired intellectual development, subcutaneous calcifications and peripheral neuropathy. They were identified with homozygous variant in PSMC3 gene (c.1127 + 337A>G). Functional studies in patient fibroblast cells suggested that the patient PSMC3 variant is responsible for proteasome failure affecting protein homeostasis under stress conditions. This is also supported by evidence from zebrafish models, where PSMC3 knockout has reproduced the human phenotype with inner ear development anomalies as well as cataracts. PMID:37256937 - 23 individuals with neurodevelopmental disorder were identified with 15 different de novo missense variants. Apart from one child (patient 2), all others had developmental delay characterised by speech delay (19/19) alone or with intellectual disability (16/18) and motor delay (15/19). 9/19 patients had hearing loss, of which two were labelled as sensorineural and one was labelled as conductive. In addition, structural modeling as well as proteomic and transcriptomic analyses of T cells derived from patients with PSMC3 variants implicated the PSMC3 variants in proteasome dysfunction through disruption of substrate translocation, induction of proteotoxic stress, and alterations in proteins controlling developmental and innate immune program. The phenotype caused by recessive PSMC3 variants has been reported in OMIM (MIM #619354), but not in Gene2Phenotype. However, the phenotype caused by dominant variants has not yet been reported in either resources. Sources: Literature |
