GeneDx RCV000219402 SCV000278965 uncertain significance not provided 2013-12-05 criteria provided, single submitter clinical testing To our knowledge, the K930N missense substitution has neither been published as a mutation, nor has it been reported as a benign polymorphism. This substitution was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. K930N represents a non-conservative amino acid substitution as a positively-charged Lysine residue is replaced with a neutral, polar Asparagine residue. This substitution occurs at a position in the NLRP3 protein that is highly conserved among species; however, it is not located in the NACHT/NBD domain, which is the domain where nearly all NLRP3 disease-associated mutations have been identified. Therefore, based on the currently available information, it is unclear whether K930N is a disease-causing mutation or a rare benign variant.
