CCR5 S185Shift - GET-Evidence


CCR5 S185Shift

(CCR5 185delSinsShift)

Short summary

Also known as CCR5-delta32, this variant is associated with resistance to many strains of HIV (but not all strains, only strains that use target the CCR5 protein). Heterozygotes are reported to have slower HIV progression, and homozygotes are very resistant to being infected by these strains.

Variant evidence
Computational 3

Highly disruptive effect on gene, gene product is known to be involved in HIV infection for some strains

Functional 1

PBMCs resistant to infection

Case/Control 4

See Samson M et al. 1996 (8751444).

Familial -
Clinical importance
Severity 4

Evaluated as the risk/effect of HIV infection

Treatability 4
Penetrance 1

Penetrance is estimated assuming low HIV infection rate (< 1%) — this variant would confer less than 1% decreased attributable risk of HIV infection.



Low clinical importance, protective

Genotype frequencies: seropositive (cases): /: 645, +/del32: 78, del32/del32: 0. seronegative (controls): /: 582, +/del32: 114, del32/del32: 8.

Pooling by recessive hypothesis, case+: 0, case-: 723, control+: 8, control-: 696. This has p = 0.003 using Fisher’s Exact Test.
