Variant information
Variant position:
191
The position of the amino-acid change on the UniProtKB canonical protein sequence.
Type of variant:
LB/B
The variants are classified into three categories: LP/P, LB/B and US.LP/P: likely pathogenic or pathogenic. LB/B: likely benign or benign. US: uncertain significance
Residue change:
From Glutamate (E) to Aspartate (D) at position 191 (E191D, p.Glu191Asp).
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 acidic.
The physico-chemical property of the reference and variant residues and the change implicated.
BLOSUM score:
2
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).

Polymorphism:
Genetic variations in SLC2A9 influence the variance in serum uric acid concentrations and define the serum uric acid concentration quantitative trait locus 2 (UAQTL2) [MIM:612076 ] with pronounced sex-specific effects. The proportion of the variance of serum uric acid concentrations explained by genotypes is about 1.2% in men and 6% in women, and the percentage accounted for by expression levels is 3.5% in men and 15% in women (PubMed:18327256 , PubMed:18327257 , PubMed:18842065 ). Excess serum accumulation of uric acid can lead to the development of gout (PubMed:18327256 , PubMed:18327257 ).
