message: The CCR5 article speaks about the deletion which causes CCR5Δ32. With the DNA testing company FamilyTreeDNA they call it the del32 mutution and call that a deletion mutation. So is "Δ" genetic abbr. for deletion? If so, it should be added to the article. Nagelfar 20:52, 27 February 2007 (UTC)

message: Lower case delta does not represent an infinitessimal change but rather a small finite one (as opposed to capital delta which represents any size change). 'd' is used to represent an infinitessimal change.
If there is a convention that uses delta in place of d then it would be worth mentioning that this isn't the only (nor most common) usage.  — Preceding unsigned comment added by 131.111.185.4 (talk) 13:57, 12 February 2013 (UTC)

message: "The capital letter Delta (Δ, which has the convenient form of an equilateral triangle)"
Is there any reliable source about the equilateral nature of Δ? IMHO it's only an isoceles triangle.  — Preceding unsigned comment added by 137.132.250.13 (talk) 06:07, 21 February 2013 (UTC)

message: I am unhappy about the representation of the lower case delta as δ in the lead paragraph and in some other places in the article. It is not a form I am familiar with (having studied physics and maths to degree level). It may be usual in modern Greek - I don't know - but it is commonly used in mathematics, physics, etc. simply as a name of a variable, as are other Greek letters, and in this context it normally has the represenation 𝛿. I propose to alter the first sentence to read "Delta (uppercase Δ, lowercase δ or 𝛿;..." Mike Spathaky (talk) 11:18, 16 December 2013 (UTC)
