What's the difference between autism phenotype and pdd-nos?

Descriptors: The diagnosis for all who have lack of theory of mind, qualitative impairments in social communication & reciprocal interaction, & narrow, restricted areas of interest or stereotypical movements is autistic disorder in the dsm-v. Pdd-nos is the dsm-iv term for having some, but not all, symptoms of autism. Broader autism phenotype, not a diagnosis, is having even fewer. Vaccines don't cause autism.
