Chromosomal pairs

Every person has 23 pairs of chromosomes. There are 22 pairs known as autosomes and 1 pair of sex chromosomes (X and Y). If there is an extra or a missing chromosome in any of these pairs, it is known as an aneuploidy.

Microdeletion syndromes

A microdeletion is the absence or ‘deletion’ of small amounts of chromosomal DNA. The chromosomal location and size of the deletion determines the type and severity of the syndrome present.

Sex chromosomes

Every person has 2 sex chromosomes. XX for a female genotype and XY for a male genotype. Sometimes there is an extra or missing sex chromosome, this is known as a sex chromosome aneuploidy.

Gender identification

If gender identification is requested, we can screen the sex chromosomes and report on whether the chromosomes present mean the baby is likely to be a male or a female. In twin pregnancies, it is only possible to determine if the Y chromosome is present, which if detected means at least one of the babies is likely to be a male.
