| Monogenic hearing loss v2.139 | PMP22 | Eleanor Williams Added comment: Comment on list classification: After consultation with Genomics England clinical team leaving this gene as amber as the majority of patients do not have a hearing loss phenotype, and there are also issues around the potential predictive nature of the neurological aspects if this panel was applied to a paediatric hearing loss cohort. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Monogenic hearing loss v2.129 | PMP22 | Eleanor Williams Added comment: Comment on list classification: Promoting this gene from red to amber. Three independent cases reported in which patients have Charcot-Marie-Tooth disease plus hearing loss and variants in PMP22, but waiting for feedback from Genomics England clinical team as to whether this gene is appropriate to be green as HL is part of a syndrome of features. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Eleanor Williams changed review comment from: Associated with Charcot-Marie-Tooth disease, type 1E #118300 (AD) in which hearing loss is listed as a clinical feature PMID: 12578939 - Sambuughin et al 2003 - report deafness associated with a demyelinating neuropathy in three individuals of a family in whom a novel 12bp deletion resulting in the deletion of four-amino acid deletion (115-118) in the PMP22 gene was identified (targeted sequencing of PMP22). No asymptomatic family members had the deletion nor was it detected in 55 healthy controls. PMID: 11835375 - Boerkoel et al 2002 - screened PMP22, GJB1, and MPZ contained 159 unrelated patients with primary peripheral demyelinating neuropathy or a primary peripheral axonal neuropathy and report 5 which have heterozygous variants in PMP22, 1 of which had a clinical diagnosis of CMT1 + deafness (variant 82T>C W28R). An affected sibling had the same variant. PMID: 10330345 - Kovach et al 1999 - analysis of a 7 generation family from central Illinois with autosomal dominant CMT and deafness. In the 31 affected family members, hearing loss ranged from borderline normal to profound hearing loss, with all having at least mild bilateral hearing loss by adulthood. Following haplotype analysis they sequenced PMP22 and a point mutation was found in affected individuals G->C at position 248 in exon 4 in the heterozygous state (p.Ala67Pro). PMID: 8355122 - Hamiel et al 1993 - Abstract only accessed. Describe a family with hereditary motor-sensory neuropathy with sensorineural deafness is described; the neurologic features and deafness were apparent in early childhood and infancy. Summary: 3 cases in which hearing loss is reported in CMT patients with PMP22 variants. In all cases a limited number of genes were sequenced.; to: Associated with Charcot-Marie-Tooth disease, type 1E #118300 (AD) in which hearing loss is listed as a clinical feature PMID: 12578939 - Sambuughin et al 2003 - report deafness associated with a demyelinating neuropathy in three individuals of a family in whom a novel 12bp deletion resulting in the deletion of four-amino acid deletion (115-118) in the PMP22 gene was identified (targeted sequencing of PMP22).
