In 2008, the American College of Medical Genetics published a Practice Guideline designed to assist clinicians with a logical approach to the genetic evaluation of patients diagnosed with autism and autism spectrum disorders (ASD) ( DOI: 10.1097/GIM.0b013e3186b5cc9).
Based on these recommendations the Medical Genetics Laboratories have developed a panel of tests to provide the physician with a comprehensive genetic workup for appropriate patients with ASD to obtain information about the etiology and to provide appropriate medical management as well as genetic counseling to the family.
Autism Panels Available:
- 8100 - Male Specific Comprehensive Autism Panel
Chromosomal Microarray Analysis; FMR1-Related Disorders Trinucleotide Repeat Analysis; Biochemistry 6-Plex*
- 8110 - Female Specific Comprehensive Autism Panel
Chromosomal Microarray Analysis; FMR1-Related Disorders Trinucleotide Repeat Analysis; Biochemistry 6-Plex*; MECP2-Related Disorders Sequencing and Deletion/Duplication Analysis
Biochemical Panel Available:
Individual Tests Available:
Over 30 individual tests (molecular; cytogenetic; biochemical and mitochondrial) are available to be ordered for patients requiring a more tailored genetic evaluation. Please see full listing on the AUTISM TESTING REQUISITION
Reasons for Referral:
- Determination of the genetic etiology of clinical diagnosis of ASD.
Testing Methodology:
DNA sequencing; comparative genomic hybridization; tandem mass spectroscopy; and gas chromatography/mass spectroscopy.
