This assay is not designed or validated for the detection of somatic mosaicism or somatic mutations. Get statistics, learn how it affects kids, and more. Finding a genetic reason for ASD provides having needed services, identifying underlying medical risks associated with diagnosis and decreasing morbidity. trinucleotides or hexanucleotides), alterations in most regulatory regions (promoter regions) or deep intronic regions (greater than 20bp from an exon). Autism spectrum disorder is a neurodevelopmental condition that can affect a person’s ability to communicate. This assay will not detect certain types of genomic alterations which may cause disease such as, but not limited to, translocations or inversions, repeat expansions (eg. Overall, this work will focus on genetic evaluation and counseling for NDDs that have the greatest likelihood to yield an identifiable genetic causenamely, global developmental delay (GDD), intellectual disability (ID), and autism spectrum disorder (ASD)highlighting the importance of genetic counseling and ongoing follow-up. Identified putative deletions or duplications are confirmed by an orthogonal method (qPCR or MLPA). Sometimes a health care provider may order whole exome sequencing (WES), which examines a persons DNA to look for genetic changes associated with ASD. If ordered, deletion/duplication analysis can identify alterations of genomic regions which include one whole gene (buccal swab specimens and whole blood specimens) and are two or more contiguous exons in size (whole blood specimens only) single exon deletions or duplications may occasionally be identified, but are not routinely detected by this test. Sanger sequencing is used to confirm variants with low quality scores and to meet coverage standards. As defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR), the spectrum includes diverse phenotypic manifestations, s. Although next generation sequencing technologies and our bioinformatics analysis significantly reduce the contribution of pseudogene sequences or other highly-homologous sequences, these may still occasionally interfere with the technical ability of the assay to identify pathogenic variant alleles in both sequencing and deletion/duplication analyses. Autism spectrum disorders (ASDs) are characterized by impaired socialization, reduced communication, and restricted, repetitive, or stereotyped activities and interests. This analysis is performed by Next Generation Sequencing (NGS) and is designed to examine coding regions and splicing junctions. With this test, we can find the potential cause of autism about 10 to 30. All sequencing technologies have limitations. Exome sequencing is a more detailed test that looks at the DNA that codes for genes.
