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

Sensitivity for SNVs
Specificity for SNVs
Positive predictive value for SNVs
Clinical sensitivity for structural variants

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.
