UniProtKB/Swiss-Prot O15553: Variant p.Met694Val

Gene: MEFV
Chromosomal location: 16p13.3
Variant information

Variant position:  694
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Type of variant:  Disease [Disclaimer]
The variants are classified into three categories: Disease, Polymorphism and Unclassified.
  • Disease: Variants have been found in patients and disease-association is reported in literature. However, this classification is not a definitive assessment of variant pathogenicity.
  • Polymorphism: No disease-association has been reported.
  • Unclassified: Variants have been found in patients but disease-association remains unclear.

Residue change:  From Methionine (M) to Valine (V) at position 694 (M694V, p.Met694Val).
Indicates the amino acid change of the variant. The one-letter and three-letter codes for amino acids used in UniProtKB/Swiss-Prot are those adopted by the commission on Biochemical Nomenclature of the IUPAC-IUB.

Physico-chemical properties:  Similar physico-chemical property. Both residues are medium size and hydrophobic.
The physico-chemical property of the reference and variant residues and the change implicated.

BLOSUM score:  1
The score within a Blosum matrix for the corresponding wild-type to variant amino acid change. The log-odds score measures the logarithm for the ratio of the likelihood of two amino acids appearing by chance. The Blosum62 substitution matrix is used. This substitution matrix contains scores for all possible exchanges of one amino acid with another:
  • Lowest score: -4 (low probability of substitution).
  • Highest score: 11 (high probability of substitution).

Involvement in disease:  Familial Mediterranean fever, autosomal dominant (ADFMF) [MIM:134610]: A hereditary periodic fever syndrome characterized by periodic fever, serosal inflammation and pain in the abdomen, chest or joints as seen also in the autosomal recessive form of the disease. It is associated with reactive renal amyloidosis and characterized by colchicine unresponsiveness. {ECO:0000269|PubMed:10787449, ECO:0000269|PubMed:14679589}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Involvement in disease:  Familial Mediterranean fever, autosomal recessive (ARFMF) [MIM:249100]: A hereditary periodic fever syndrome characterized by recurrent episodic fever, serosal inflammation and pain in the abdomen, chest or joints. It is frequently complicated by reactive amyloidosis, which leads to renal failure and can be prophylactically treated with colchicine. {ECO:0000269|PubMed:10024914, ECO:0000269|PubMed:10090880, ECO:0000269|PubMed:10234504, ECO:0000269|PubMed:10364520, ECO:0000269|PubMed:10612841, ECO:0000269|PubMed:10842288, ECO:0000269|PubMed:10854105, ECO:0000269|PubMed:11470495, ECO:0000269|PubMed:15024744, ECO:0000269|PubMed:16378925, ECO:0000269|PubMed:16730661, ECO:0000269|PubMed:23031807, ECO:0000269|PubMed:24929125, ECO:0000269|PubMed:9288094, ECO:0000269|PubMed:9288758, ECO:0000269|PubMed:9668175}.

Variant description:  In arFMF and adFMF; very common mutation particularly in North African Jews; can be associated with amyloidosis development; reduced interaction with CASP1 (PubMed:16785446); no effect on interaction with CASP1, CASP5, NLRP1, NLRP2 or NLRP3 (PubMed:17431422).
