Genomic Unity® Prenatal Analysis
Test Code – RPG001
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.
When to Order
Order this test when amniocentesis has been determined to be medically necessary due to ultrasound abnormalities.
- 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.
- 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 fluorescent in situ hybridization (FISH) analysis of chromosomes: 13, 18, 21, X, and Y.
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.

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