Hereditary neuropathy or pain disorder
Gene: GJB1
Multiple C5s in Bristol. Also well established from looking at HGMD. PMID: 8266101 - early paper identified 7 different mutations in affected persons from 8 families with X-linked dominant Charcot-Marie-Tooth diseaseCreated: 29 Apr 2019, 12:30 p.m.
Mode of inheritance
X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)
Phenotypes
Charcot Marie Tooth neuropathy, X linked dominant, 1, 302800 ; Charcot-Marie-Tooth, X-linked
Publications
Variants in this GENE are reported as part of current diagnostic practice

Sequencing should also cover at least 600 bp upstream of START site (ChrX(GRCh37):g.70442959_70443558) to capture non-coding/promoter mutations, accounting for >10% of GJB1 mutations (PMID 28283593)Created: 29 Apr 2019, 9:20 a.m.
