Variant summary

Our verdict is Pathogenic. The variant received 16 ACMG points: 16P and 0B. PM1PM5PP3_StrongPP5_Very_Strong

The NM_000243.3(MEFV):c.2082G>A(p.Met694Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000083 in 1,614,176 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M694V) has been classified as Likely pathogenic.

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 was made for transcript

Our verdict: Pathogenic. The variant received 16 ACMG points.

PM1

In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 3 benign, 12 uncertain in NM_000243.3

PM5

Other missense variant is known to change same aminoacid residue: Variant chr16-3243407-T-C is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 2538.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.953

PP5

Variant 16-3243405-C-T is Pathogenic according to our data. Variant chr16-3243405-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 2539.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
