Norway's current king, Harald V, is the son of a first cousin marriage. His father was also the son of a first cousin marriage. Okay, he has a big nose and a rather pronounced case of male pattern baldness, but I don't think you can call him deformed. He's also somewhere around average on the intelligence scale.

Intermarriage among the royal families of Europe was the normal thing up until the early 20th century. You can certainly find examples of children born with serious problems because of that, and even today certain traits (like dyslexia) seem to be more widespread among the royals than the general population, likely because of the pedigree collapse issues. But most of the babies of these first cousin marriages were born quite normal. Cousin marriages make it more likely that the bad stuff hidden in the genes will come out in the babies - but they do not create new mutations.
