Introns are not non-coding segments of DNA. They are not part of a gene. A gene may be made of several segments not physically adjacent to each other.

Genes do have introns. Introns are the non-coding parts of the DNA, and they often times regulate the expression of the genes they are within. Through a process called splicing, the introns are then cut out of the gene to form the mature messenger RNA molecule (mRNA), which codes for the gene product (a protein).

Actually they do. Introns are the non-coding portions of genes. See this link for details:
