Clinically-Relevant Mutations and Pathophysiology
Disease:  Human immunodeficiency virus type 1, susceptibility to
OMIM:  609423
References: 
Mutations not determined
Biologically Significant Variants
Type:  Splice variants.
Species:  Human
Description:  Two splice variants of the human CCR2 gene have been identified, CCR2-B being the more predominant form of the receptor, and CCR2-A having a shorter C-terminus with impaired receptor trafficking to the cell surface.
References:  7,51,59,68,74
Type:  Single nucleotide polymorphism.
Species:  Human
Description:  A Val64 -> Ile polymorphism in the CCR2 gene has been identified in humans. The Ile substituted CCR2-A receptor variant is thought to be associated with a delay in disease progression from HIV-1 to AIDS perhaps by interfering with the cell surface expression of the CCR5 receptor.
References:  40,46-47,51,64,66
Type:  Single nucleotide polymorphism.
Species:  Human
Description:  The Val64 -> Ile polymorphism may be associated with a lower risk for the development of sarcoidosis.
References:  27,52
Type:  Single nucleotide polymorphism.
Species:  Human
Description:  The Val64 -> Ile polymorphism may provide protection in mother-to-infant HIV-1 transmission.
References:  44
Type:  Single nucleotide polymorphism.
Species:  Human
Description:  The Val64 -> Ile polymorphism may be associated with a reduced risk of coronary artery disease.
References:  67,71
Type:  Single nucleotide polymorphism.
Species:  Human
Description:  The Val64 -> Ile polymorphism may be associated with an reduced loss of bone mineral density in middle-aged men and postmenopausal women.
References:  75
Type:  Single nucleotide polymorphism.
Species:  Human
Description:  The Val64 -> Ile polymorphism may be linked to increased risk of myocardial infarction and heart failure.
References:  48,53
Type:  Single nucleotide polymorphism.
Species:  Human
Description:  The Val64 -> Ile polymorphism may be linked to the development of breast cancer.
References:  77
Type:  Single nucleotide polymorphism.
Species:  Human
Description:  The Val64 -> Ile polymorphism may have a protective effect on the development of Alzheimer's disease.
References:  23
Type:  Single nucleotide polymorphism.
Species:  Human
Description:  The Val64 -> Ile polymorphism may be linked to a decreased risk of developing invasive cervical cancer.
