Researchers are looking for mothers/daughters of individuals with X-linked ichthyosis who have suffered mental health problems after giving birth. Work undertaken at Cardiff University has recently suggested that women who have reduced levels of the molecule steroid sulphatase may be at increased risk of developing postnatal mental health problems. In order to see whether this might be the case, we would like to identify the mothers or daughters of individuals with confirmed/suspected X-linked ichthyosis (caused by steroid sulphatase deficiency), who have experienced mental health problems shortly after giving birth and who would be interested in participating in future research. If you meet these criteria and wish to be sent further information, please contact: Dr William Davies, Cardiff University School of Psychology, TowerBuilding, Park Place, CardiffCF10 3AT, Tel: +44-(0)29-2087-0152, e-mail:
