Hereditary neuropathy or pain disorder
Gene: PSMC3
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.
