CCR5-Δ32 (or CCR5-D32 or CCR5 delta 32) is an allele of CCR5. [42] [43] CCR5 Δ32 is a 32-base-pair deletion that introduces a premature stop codon into the CCR5 receptor locus, resulting in a nonfunctional receptor. [44] [45] CCR5 is required for M-tropic HIV-1 virus entry. [46]
The absence of such receptors, or rather the shortening of them to the point of being inoperable, is known as the delta 32 mutation. [4] This mutation is linked to groups of people that have been exposed to HIV but remain uninfected such as some offspring of HIV positive mothers, health officials, and sex workers. [5]

A newer theory suggests that the selective pressure on the CCR5 Delta 32 mutation was caused by smallpox instead of the bubonic plague. [117] Malaria resistance: An example of a harmful mutation is sickle-cell disease, a blood disorder in which the body produces an abnormal type of the oxygen-carrying substance haemoglobin in the red blood cells.
India said on Wednesday it has found around 40 cases of the Delta coronavirus variant carrying a mutation that appears to make it more transmissible, and advised states to increase testing.
