1533 - Genome-wide microarray testing for pregnancies with major foetal structual abnormalities detected by ultrasound

Page last updated: 02 March 2020

Application Detail

Status

Open

Description of Medical Service

Microarray is a general term used for a number of different complex technologies that are used to study the whole genome for both loss of DNA segments (deletion) and gain of DNA segments (duplication). These deletions and duplications are collectively referred to as copy-number variations. Microarray can detect copy-number variations that are too smallto be seen by conventional chromosome analysis.

Description of Medical Condition

Major foetal ultrasound abnormalities can often result from the genotype of the foetus. Investigation can involve invasive testing with karyotype testing often used to identify chromosomal anomalies. The range of medical conditions resulting from genetic abnormalities is broad and encompasses physical and intellectual conditions that can present significantly at birth or later in life. It is therefore difficult to describe the full range of medical conditions that might be detected by micro-array testing.

Reason for Application

Amendment to MBS item
Extend genome-wide microarray testing (MBS item 73292) to use in one additional population and setting:
• in antenatal testing, when invasive testing is undertaken in pregnancy to investigate a pregnancy where there are major foetal ultrasound abnormalities (in preference to karyotype testing).
