Genes affected
MEFV (HGNC:6998): (MEFV innate immunity regulator, pyrin) This gene encodes a protein, also known as pyrin or marenostrin, that is an important modulator of innate immunity. Mutations in this gene are associated with Mediterranean fever, a hereditary periodic fever syndrome. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.84).
BP6
Variant 16-3249599-C-T is Benign according to our data. Variant chr16-3249599-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 527806.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=6, Uncertain_significance=1}.
BP7
Synonymous conserved (PhyloP=-0.907 with no splicing effect.
BS2
High Homozygotes in GnomAdExome4 at 5 SD geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The variant is not listed in the ClinVar database, but is listed in the dbSNP variant database (rs11466022) with an allele frequency of 0.01050 percent (29/276138 alleles) in the Genome Aggregation Database. The nucleotide at this position is not well conserved across species and computational algorithms (SpliceSiteFinder-like, MaxEntScan, NNSplice, GeneSplicer, Human Splicing Finder) predict this variant is tolerated. Considering available information, this variant is classified as likely benign. -
