Conclusions: Family pedigree (D) of this patient with compound heterozygous mutation (R523>X, K655>R) of SCN9A including de novo splicing mutation IVS8-2A>G not found in his unaffected siblings or parents. Here we describe a patient with CIP with a new mutation in SCN9A not described yet. NIH Congenital insensitivity to pain (OMIM 243000) is an extremely rare disorder caused by loss-of-function mutations in SCN9A encoding Nav1.7. 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. 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. Results: 4 The SCN9A gene determines the formation of the sodium Sodium channels transport positively charged sodium atoms (sodium ions) into cells and play a key role in a cell's ability to generate and transmit electrical signals. 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.

Mansouri M, Chafai Elalaoui S, Ouled Amar Bencheikh B, El Alloussi M, Dion PA, Sefiani A, Rouleau GA. Pediatr Neurol. Congenital insensitivity to pain is caused by a mutation on the SCN9A gene, and is inherited as an autosomal recessive trait. As a result, a shortened, nonfunctional subunit is produced which cannot be incorporated into the channel, leading to a loss of functional NaV1.7 sodium channels. 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. Pain Rep. 2020 Jul 27;5(4):e826.
