Variant information Variant position:

675 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 Proline (P) to Serine (S) at position 675 (P675S, p.Pro675Ser). 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 medium size and hydrophobic (P) to small size and polar (S) 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:

Allelic variants in IL4RA are associated with a susceptibility to atopy, an immunological condition that can lead to clinical symptoms such as allergic rhinitis, sinusitis, asthma and eczema.Allelic variants in IL4RA are associated with cedar pollen sensitization. Individuals develop Japanese cedar pollinosis with increased exposure to cedar pollen. Japanese cedar pollinosis is a type I allergic disease with ocular and nasal symptoms that develop paroxysmally on contact with Japanese cedar pollen. These symptoms, which occur seasonally each year, are typical features of allergic rhinitis, such as sneezing, excessive nasal secretion, nasal congestion, and conjunctival itching. - Additional information on the polymorphism described.
