Genomic Unity® Intellectual Disability Analysis
Test Code – NR001
Intellectual disability is a neurodevelopmental disorder defined by limitations in intellectual functioning and adaptive behavior that begins before 18 years of age. Intellectual disability can be isolated or non-syndromic, as well as syndromic. In syndromic intellectual disability, accompanying features may include distinct facial features, hypotonia, seizures, congenital contractures, ataxia, and more.
Genomic Unity® Intellectual Disability Analysis uses a whole genome sequencing platform to diagnose genetic causes of intellectual disability by detecting copy number variants and duplication/deletion analysis of the entire genome, sequence analysis in a set of 14 genes, and repeat expansion analysis of AFF2 and FMR1. Testing includes autosomal and X-linked forms of intellectual disability.
When to order
Order this test when clinical symptoms are consistent with a form of intellectual disability, with or without additional clinical symptoms. You also have the option to reflex up to Genomic Unity® Exome Analysis or Genomic Unity® Exome Plus Analysis if targeted analysis is non-diagnostic.
- Constitutional genome-wide copy number variant (CNV) analysis (copy number variants, duplications/deletions, regions of homozygosity, inversions, mobile element insertions, and aneuploidy)
- Sequence analysis of intellectual disability-associated genes (single nucleotide variants, deletions, insertions, and characterized intronic variants)
- Short tandem repeat (STR) analysis the AFF2 and FMR1 genes
