Variant information Variant position:

540 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 Arginine (R) to Glutamine (Q) at position 540 (R540Q, p.Arg540Gln). 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:

Change from large size and basic (R) to medium size and polar (Q) 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).

Polymorphism:

Genetic variations in GCKR define the fasting plasma glucose levels quantitative trait locus 5 (FGQTL5) [MIM:613463] (PubMed:18556336, PubMed:18678614). The normal fasting plasma glucose level is defined as less than 100 mg glucose per deciliter plasma (5.55 mmol per liter). Higher fasting plasma glucose levels predict type 2 diabetes in young adults and increases the risk of mortality (PubMed:18556336, PubMed:18678614). Additional information on the polymorphism described.
