IriSight™️ Prenatal Analysis
Test Code – RPG001
Test Description
IrisightTM Prenatal Analysis is a clinical diagnostic test designed to identify genetic variants that correlate with clinical symptoms manifested in a fetus or a pregnancy, or that lead to severe, early-onset genetic disorders.
When to Order
Order this test when amniocentesis has been determined to be medically necessary due to ultrasound abnormalities.
Included Analyses
- Genome-wide sequence analysis sequence analysis including single nucleotide variants, deletions/insertions, and characterized intronic variants.
- Genome-wide structural variant analysis including: copy number variants, duplications/deletions, regions of homozygosity, uniparental disomy, mobile element insertions, inversions, and aneuploidy.
- Mitochondrial genome sequence analysis with heteroplasmy and large deletion analysis.
- Short tandem repeat (STR) analysis of four genes: AR, DMPK, FMR1, and FXN.
- Maternal cell contamination (MCC) is determined for quality control purposes. Parental inheritance will be identified for reported variants if available.
Test Performance
Short tandem repeats:
Due to the variable nature of repetitive sequences and sequence-specific differences in detection and repeat evaluation, orthogonal confirmation is performed on a case-by-case basis. Reportable pathogenic or intermediate repeat expansions may be reported with or without repeat count.
