Variant information Variant position:

165 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 Tyrosine (Y) to Cysteine (C) at position 165 (Y165C, p.Tyr165Cys). 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 aromatic (Y) to medium size and polar (C) 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).

Sequence information Variant position:

165 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Protein sequence length:

174 The length of the canonical sequence.
Location on the sequence:

LYDYGRWLVVVTGWTLFVGV Y IVIEIARGN The residue change on the sequence. Unless the variant is located at the beginning or at the end of the protein sequence, both residues upstream (20) and downstream (20) of the variant will be shown.
Residue conservation:

The multiple alignment of the region surrounding the variant against various orthologous sequences.
