UniProtKB/Swiss-Prot P98161: Variant p.Ala3954Pro

Polycystin-1
Gene: PKD1
Variant information

Variant position:  3954
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Type of variant:  Unclassified
The variants are classified into three categories: Disease, Polymorphism and Unclassified.
  • Disease: Variants implicated in disease according to literature reports.
  • Polymorphism: Variants not reported to be implicated in disease.
  • Unclassified: Variants with uncertain implication in disease according to literature reports. Evidence against or in favor of a pathogenic role is limited and/or conflicting.

Residue change:  From Alanine (A) to Proline (P) at position 3954 (A3954P, p.Ala3954Pro).
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 small size and hydrophobic (A) to medium size and hydrophobic (P)
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:  Polycystic kidney disease 1 with or without polycystic liver disease (PKD1) [MIM:173900]: An autosomal dominant disorder characterized by renal cysts, liver cysts and intracranial aneurysm. Clinical variability is due to differences in the rate of loss of glomerular filtration, the age of reaching end-stage renal disease and the occurrence of hypertension, symptomatic extrarenal cysts, and subarachnoid hemorrhage from intracranial 'berry' aneurysm. {ECO:0000269|PubMed:10200984, ECO:0000269|PubMed:10364515, ECO:0000269|PubMed:10577909, ECO:0000269|PubMed:10647901, ECO:0000269|PubMed:10729710, ECO:0000269|PubMed:10854095, ECO:0000269|PubMed:10923040, ECO:0000269|PubMed:10987650, ECO:0000269|PubMed:11012875, ECO:0000269|PubMed:11058904, ECO:0000269|PubMed:11115377, ECO:0000269|PubMed:11216660, ECO:0000269|PubMed:11316854, ECO:0000269|PubMed:11558899, ECO:0000269|PubMed:11571556, ECO:0000269|PubMed:11691639, ECO:0000269|PubMed:11773467, ECO:0000269|PubMed:11857740, ECO:0000269|PubMed:11967008, ECO:0000269|PubMed:12007219, ECO:0000269|PubMed:12070253, ECO:0000269|PubMed:12220456, ECO:0000269|PubMed:12482949, ECO:0000269|PubMed:12842373, ECO:0000269|PubMed:15772804, ECO:0000269|PubMed:18837007, ECO:0000269|PubMed:21115670, ECO:0000269|PubMed:22508176, ECO:0000269|PubMed:8554072, ECO:0000269|PubMed:9199561, ECO:0000269|PubMed:9259200, ECO:0000269|PubMed:9285784, ECO:0000269|PubMed:9521593, ECO:0000269|PubMed:9921908}.
