In the ®rst trimester of pregnancy the biochemical markers free b-hCG and pregnancy associated plasma protein-A (PAPP-A) are used for the prenatal screening of trisomy 21, either alone or in combination with nuchal translucency (NT) thickness. In this study, I have analysed the distribution of these

✦ Synopsis
In Greece and other Mediterranean countries up to 10% of the population are carriers of beta-thalassaemia and this is the most common indication for chorion villus sampling (CVS): Cytogenetic analysis of the samples is not carried out routinely, but is confined only to women aged 35 years or more. In this report we present a case that illustrates how the measurement of fetal nuchal translucency may be useful in selecting the cases where in addition to the DNA analysis for beta-thalassaemia the samples can be tested for chromosomal defects.

In a study of 2923 normal pregnancies and 203 pregnancies affected by trisomy 21 we have shown a signi®cant difference in the median MoM of the markers: fetal nuchal translucency, maternal serum free b-hCG and PAPP-A in the presence of a female fetus compared with a male fetus. For maternal serum fr
