birth mark or something?

i had a seedling sprout up a couple weeks ago, and when the main leaves (not the cotyledons?) came out, one of them had a part of leaf that looked really droopy. n its been like that ever since. is that gonna have any effect on my plant?
 
its about 6 inches tall. i really think its just a wierd leaf. i can try to post a pic, but its not drooping, its just a wierd tweak in my leaf.

you can see it much better in the 1st pic on the lower leaf, about the middle and to the side of the leaf. all the other leaves look normal.
