Congenital Analgesia and Mutations on SCN9A Gene Congenital insensitivity to pain (CIP) represents an extremely rare disorder in which a person cannot feel the pain. Individuals who are diagnosed with congenital insensitivity to pain usually present severely impaired pain perception, and in some cases, they also manifest a decreased sense of smell (anosmia). PRDM12 gene is normally switched on during the development of pain-sensing nerve cells. 2019 Jan-Dec;15:1744806919881846. doi: 10.1177/1744806919881846.

Loss of function mutations in SCN9A gene causes truncation of the encoded sodium channel Nav 1.7 protein, resulting in channelopathy-associated autosomal recessive congenital insensitivity to pain. Some of these mutations are SX, I X, W X, MI, and M L [ , ]. 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.

Inactivating gene mutations for Na v1.7 are responsible for congenital insensitivity to pain, a disorder characterized by a complete lack of pain perception. 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. eCollection 2020.

We sought to investigate for SCN9A mutations in a clinically well-characterised cohort of patients with CIP and erythromelalgia. | 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. Yuan JH, Schulman BR, Effraim PR, Sulayman DH, Jacobs DS, Waxman SG. 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. Congenital insensitivity to pain with anhidrosis (CIPA) is a rare autosomal recessive disease characterized by anhidrosis, insensitivity to noxious stimuli, and mental retardation. It is caused by mutation of the SCN9A gene located on chromosome 2q24.3. Mutations of the gene SCN9A, which codes the α subunit of NaV1.7 channels, are associated with pain perception disorders (primary erythermalgia, congenital analgesia, and paroxysmal pain disorder). eCollection 2020 Jul-Aug. Pflugers Arch. J Am Acad Dermatol 2006;55:519–22 what situations and behaviours are likely to lead to injury. (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.

See this image and copyright information in PMC. Congenital insensitivity to pain (CIP) is characterized by the inability to experience inflammatory, heat, or visceral pain sensations. The SCN9A gene mutations that cause congenital insensitivity to pain create a premature stop signal in the instructions for making the alpha subunit of the NaV1.7 sodium channel. It is considered that the SCN9A gene mutations may cause variations in sensitivity to pain, from complete insensitivity to extreme sensitivity. Mutations in the SCN9A gene cause congenital insensitivity to pain. Epub 2018 Jul 23.
