Genomic Unity® Prenatal Analysis


Genomic Unity® 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.

Order this test when amniocentesis has been determined to be medically necessary due to ultrasound abnormalities.

  • Genome-wide sequence analysis of pathogenic/likely pathogenic variants that correlate with prenatal findings and/or are predicted to result in severe, early onset genetic disorders.
  • Genome-wide structural variant analysis including: copy number variants, duplications/deletions, regions of homozygosity, mobile element insertions, inversions, and aneuploidy
  • STR analysis of: AR, DMPK, FMR1, FXN 
  • Mitochondrial genome sequence and large deletion analysis

Optionally includes: 

  • Variants of Uncertain Significance (VUS) if correlated with the clinical symptoms of the fetus, the pregnancy, and/or the family history
  • ACMG Secondary Findings 
  • Rapid FISH analysis of chromosomes 13, 18, 21, X and Y 

Maternal cell contamination (MCC) is determined for quality control purposes. Parental inheritance will be identified for reported variants.

  • 81415, 81416 (xN), 81229, 81265
  • Optional - 81425, 81426 (xN), 81228, 81265

SNVs and Indels up to 50bp

99.1% sensitivity
99.2% positive predictive value

Structural variants:
96% clinical sensitivity

Mitochondrial variants:
Reported when homoplasmic

Short tandem repeats:
Due to the variable nature of repetitive sequence and sequence specific differences in detection, repeat evaluation and orthogonal confirmation is performed on a case-by-case basis. Reportable pathogenic or intermediate repeat expansions may be reported with or without repeat count.

Amniotic fluid - 20ml
Cultured cells
Fetal gDNA - 5μg
Parental blood - 5ml

A report will be issued within 20-30 days from sample receipt. If elected, a preliminary report based on FISH will be issued within 3-5 days for aneuploidies of 13, 18, 21, X and Y.
