Abbreviations: FCAS, familial cold autoinflaminatory syndrome; MWS, Muckle–Wells syndrome; NOMID, neonatal onset multisystem inflammatory disease; SNP, single-nucleotide polymorphism; 5′UTR, 5′ untranslated region.
Human genomic DNA from FCAS, MWS, and NOMID patients and from Caucasian and African-American controls were used for PCR and sequencing. Primers were designed using Primer3 (http://www-genome.wi.mit.edu/cgi-bin/primer/primer3_www.cgi). Variant frequency is represented as the variant allele over the total number of chromosomes sequenced. The PCR conditions and primers used to amplify and sequence the human genomic DNA are shown in Supplementary Table 2.
Variants are listed as the more common allele over the rarer allele.
Location of the variants represents the distance from the translational start site of NLRP3.
Evaluated in a population of atopic dermatitis patients and controls.22
One of the two FCAS patients sequenced was homozygous for the SNP listed, representing both of the rarer alleles.
This variant represents a single base pair deletion.
This variant represents a 63 base pair deletion.
This variant represents a single base pair insertion.
Two of the MWS patients sequenced were homozygous for the SNP listed, representing four out of the five rarer alleles.
