Possible pain-related mutation, but, may be benign
|
rs73969684, also known as c.554G>A, p.Arg185His and R185H, represents a rare variant in the SCN9A gene on chromosome 2. The minor allele is found at a frequency of around 0.003 (~1 in 300).
The significance of the minor allele is unclear. Mutations in the SCN9A gene are known to cause small fiber neuropathy and paroxysmal extreme pain disorder (often associated with yawning), but this particular mutation, rs73969684(T) - as indicated in dbSNP orientation - is reported as likely to be benign by one submitter to ClinVar. However, three publications describe several patients, most of whom are children, with this mutation and pain-related disorders.[PMID 21698661],[PMID 22826602],[PMID 24817410]
