In CIP case 6, we identified a novel, de novo splicing mutation (IVS8-2A>G); this splicing mutation compounded with a nonsense mutation (R523>X) and abolished SCN9A mRNA expression almost completely compared with his unaffected father. Genetic studies in families demonstrating recessively inherited channelopathy-associated insensitivity to pain have identified nonsense mutations that result in truncation of the voltage-gated sodium channel type IX subunit (SCN9A), a 113.5-kb gene comprising coding 26 exons. However, the expression of Nav1.7 is not restricted to Nav1.8 positive DRG neurons. Goldberg YP, Pimstone SN, Namdari R, Price N, Cohen C, Sherrington RP, Hayden MR.

Mutations in sodium-channel gene SCN9A cause a spectrum of human genetic pain disorders. SCN9A codes for the production of voltage gated sodium channels called Na v 1.7s and when there is a mutation present, these channels are as a result affected. Epub 2012 Nov 5. Two novel SCN9A mutations were identified, but frequently polymorphism variants are found which may provide susceptibility factors in pain modulation. It is considered that the SCN9A gene mutations may cause variations in sensitivity to pain, from complete insensitivity to extreme sensitivity. 2015 May 20;35(20):7674-81. doi: 10.1523/JNEUROSCI.3935-14.2015.

Congenital insensitivity to pain (CIP) is a rare autosomal recessive disorder presenting with a spectrum of clinical features caused by mutations in different genes. Conclusion: -, Davis MD, Sandroni P, Rooke TW, et al. However, in contrast to individuals with other SCN9A mutations, the observed pain insensitivity was relative and not absolute, which may be consistent with hypomorphic effects of one or both mutations. In this study, we performed a clinical and genetic analysis on the NTRK1 gene in four Korean patients with CIPA. Test Code: 737 Different mutations in the SCN9A gene causing loss of function of the voltage-gated sodium channel Nav1.7 have been reported in patients with this rare disease.

These transgenic mice specifically lack Nav1.7 in Nav1.8 positive nociceptors and showed reduced behavioural responses, specifically to acute mechanical and inflammatory pain assays. Healing, painless mutilating injuries on…, Healing, painless mutilating injuries on the extremities (A, B) of a 3-year-old boy…, NLM As these channels are likely involved in the formation and propagation of action potentials in such neurons, it is expected that a loss of function mutation in SCN9A leads to abolished nociceptive pain propagation. COVID-19 is an emerging, rapidly evolving situation. The SCN9A gene encodes a sodium channel protein required for transmission of electrical signals from particular nerves in the body to the brain. Zhang Y, Peng D, Huang B, Yang Q, Zhang Q, Chen M, Rong M, Liu Z. small depolarizations of the membrane and is involved in pain perception. (2006) thus suggested that congenital indifference to pain due to mutations in the SCN9A gene is actually a form of insensitivity to pain since the defect is due to a channelopathy that is not normally detected by routine histopathology.

A different mutation in "SCN9A" causes congenital insensitivity to pain. 15 Despite a large number of SCN9A mutations being reported in this highly polymorphic gene, 16 how frequently these mutations occur in these disorders is mostly unknown. Klein CJ, Wu Y, Kilfoyle DH, Sandroni P, Davis MD, Gavrilova RH, Low PA, Dyck PJ. Here we describe a patient with CIP with a new mutation in SCN9A not described yet. Arch Dermatol 2003;139:1337–43 Author information: (1)Department of Neurology, Division of Peripheral Nerve Diseases, Mayo Clinic, Rochester, MN 55905, USA. We also found a splicing junction variant (IVS24-7delGTTT) in all 19 patients, this splicing variant was previously considered casual for CIP, but IVS24-7delGTTT was in fact the major allele in Caucasian populations. eds.
