Description

Cell-Free DNA and Cell-Free Fetal DNA

Cell-free DNA fragments (cfDNA) are short fragments of DNA which can be found circulating in the blood. During pregnancy, cfDNA fragments originating from both the mother and fetus are present in maternal blood circulation. Cell-free fetal DNA (cfDNA) is present only as a minor component of the total cfDNA in maternal plasma, which poses a significant technical challenge for some NIPT detection methods.

How does NIFTY® work?

The NIFTY test requires taking a small maternal blood sample of 10ml. cfDNA in the maternal blood is then analysed to detect for chromosomal abnormality. If aneuploidy is present, small excesses or deficits in counts of the affected chromosome will be detected.

NIFTY effectively resolves the difficulty in measuring the small increments in the specific chromosome DNA concentration through the use of massively parallel sequencing technology (MPS).  This means NIFTY sequences millions of fragments of both fetal and maternal DNA from each sample. Using whole-genome sequencing technology and four different proprietary bioinformatics analysis pipelines,  the  NIFTY  test is able to analyse data across the entire genome and compare chromosomes in the tested sample against optimal reference chromosomes to accurately determine the presence of genetic abnormality.

As opposed to the ‘targeted sequencing’ methods employed by some other NIPT tests, the NIFTY methodology allows for highly accurate results irrespective of the clinical symptoms of the patient, and a broader range of testing options including for trisomy, sex chromosomal aneuploidy and deletion syndromes.

Genetic Conditions Tested by NIFTY

Trisomies

A trisomy is a type of aneuploidy in which there are three chromosomes instead of the usual pair. Trisomy 21 (Down syndrome), Trisomy 18 (Edwards syndrome) and Trisomy 13 (Patau syndrome) are the three most commonly occurring autosomal chromosome aneuploidies in live births. These chromosomal conditions are caused by the presence of an extra copy or partial copy of chromosome 21, 18 or 13 respectively. This additional genetic material can cause dysmorphic features, congenital malformation and different degrees of intellectual disability.

Deletion Syndromes

Deletion syndromes are defined as a group of clinically recognisable disorders characterised by a small deletion of a chromosomal segment. The size and position of the deletion determine which clinical features are manifested and how severe they are.

Clinical features of deletions can include developmental delays and intellectual disability, growth differences, behavioural problems, feeding difficulties, low muscle tone, seizures, dysmorphic features and a pattern of varying malformations.

Sex Chromosomal Aneuploidies

Sex chromosome aneuploidy is defined as a numeric abnormality of an X or Y chromosome, with addition or loss of an entire X or Y chromosome. Although most cases of sex chromosome aneuploidies are generally mild without intellectual disability, some have a well-established phenotype that can include physical abnormalities, learning delays and infertility.
