Doctrine: Heresy of Mormonism Pt 1

When researching the fastest growing “religions” both in the U.S. & the world I came across the following quote:

“According to the records of The Church of Jesus Christ of Latter-day Saints, its membership has grown every decade since its beginning in the 1830s, that it is among the top ten largest Christian denominations in the U.S. and that it was the fastest growing church in the U.S. in 2012.“

Is The Church of Jesus Christ of Latter-day Saints a “Christian” denomination?
