Itachi has two chakra natures, them being Fire and Water.
A Kekkei Genkai is a special ability found in certain clans, they are passed down family lines rather than learned. Hashirama Senju's Wood Release, and the Yuki clan's Ice Release. are two examples, the Uchiha Clan's Sharingan and the Hyuga clan's Byakugan are two ocular kekkei genkai. Despite being called bloodline limits, there are ways for outsiders to gain those powers. Sharingan and Rinnegan eyes can be transplanted, while the cells of Hashirama Senju have been used in various different ways, enabling people such as Yamato to use Wood Release.
Hells yeah. Nara, Yamanaka, Akimichi, Inuzuka, Aburame, Uzumaki, Fuuma, Hatake, Yuuhi, Sarutobi, Haruno (I guess). Nearly everyone with a surname belongs to a clan.
This might be a spoiler, but Sasuke kills Danzo because him and the other elders around the third hokages. People ordered itachi to kill the uchiha clan. Itachi was only staying loyal to the leaf village, but he left Sasuke alive and told the hidden leaf to keep him safe.
well i already know that itachi and Tobi have the kekki genkai of the uchiha...ans ithink pain and his rennagan are a kekki genkai
NO!
no sauske rules
So far there has been no mention of a Haruno clan.
The Sharingan is a kekkai genkai - or bloodline limit - which is passed down in the Uchiha Clan. They are the red eyes that Sasuke, Kakashi and Madara often use. It's said to be an off shoot of the Rinnegan, which were the eyes of the Rikodou Sennin, the man who invented all Jutsu.
Sakura's clan is the Haruno clan
No, the Sharingan is the kekkai genkai (bloodline limit) of the Uchiha Clan which came from the Sage of Six Paths Rinnegan. The Sage himself was the one who created the Kyuubi and the other bijou out of the ten-tails chakra, to prevent it being released when he died.
The Haruno clan does not exist. umh..maybe this can help, http://forums.narutofan.com/showthread.php?t=187149
Susanno is an ability created by itachi uchiha with his sharingan, it is a demon with the weapons of a god.And the power can only be used by users of the mangeykou sharingan and a kekkai genkai.
In Japanese culture, every family is considered a "Clan" even if it doesn't have a Kekkei Genkai. So yes, Hatake is a real clan.

The symbol on Sakura Haruno's clothes is a stylized cherry blossom, which represents her name "Sakura", meaning cherry blossom in Japanese. In the Naruto series, it is not tied to any particular clan affiliation for her character.
The Kaguya Clan is now an extinct clan. Every Clan member, excluding Kimimaro was killed off by Kirigakure (Village Hidden in the Mist). A few of the members, like Kimimaro possessed the Kekkai Genkai Shikotsumyaku, which allowed them to manipulate their bone structure. By infusing calcium with chakra, they can control the growth and properties of their bones freely. This allows them to create weapons out of their bones and shoot pieces of their bones as projectiles. When a bone is removed, it immediately regenerates, as well as the skin.
