Abstract
Autism spectrum disorder (ASD) Autism is a significant disease that has spread in recent decades; Autism is a result of a severe disability, evolutionary behavioral syndrome. Recently autism has increased in Iraq, and because of the lack of studies in this field, in the present study In this study, we investigate the genetic defects in the chromosomes of children with autism using specific probes detected by the FISH technique. Seventy biological samples (blood) were collected from children with autism from different areas around Baghdad. Advanced genetic tests will be done, including karyotype and FISH technique. Results showed chromosomal aberrations in specific sites in chromosomes represented by deletion in autistic cases (100%), where it was commonplace in sites 5p15.33-p15.2; 7q31.1-q1.31; 7q31.1-q32.2; 15q11.2-q13.3 for males and 18q21.32-q23; Xp22.33- p22.31 for females. In conclusion, the current study showed the significant value of karyotyping and FISH technique in diagnosing chromosomal deflections in autism patients.
