Invitae RCV001391018 SCV001592934 pathogenic Neuropathy, hereditary sensory and autonomic, type 2A; Generalized epilepsy with febrile seizures plus, type 7 2020-10-25 criteria provided, single submitter clinical testing Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in SCN9A are known to be pathogenic (PMID: 17470132, 19304393). For these reasons, this variant has been classified as Pathogenic. This variant has been observed in individual(s) with clinical features of autosomal recessive hereditary sensory and autonomic neuropathy (Invitae). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (ExAC no frequency). This sequence change affects a donor splice site in intron 20 of the SCN9A gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product.
