Patient discussion about phenotype.

Q. Can anyone with experience help me to know what the clinical phenotype of autism is? I am new to the medical field and I have been here for 3 months. Can anyone with experience help me to know what the clinical phenotype of autism is?

A. I welcome you to my favorite choice. This field is really very satisfying while we serve others for their good. Because of the similarities and differences among people with different forms of autism, health care professionals now view autism as having a broader clinical phenotype than was once thought. The expanded phenotype goes beyond the standard definition for autism, to include, as the DSM-IV states, a range of impairments rather than the absolute presence or absence of a certain behavior or symptom (DSM 1994).The DSM-IV uses the terms “pervasive developmental disorder (PDD)” and “autism spectrum disorder (ASD)” to describe five variations of autistic behavior; the International Classification of Disease (ICD), published by the World Health Organization (WHO) , has eight variations of PDD.
