متن کاملLoss of heterozygosity at cylindromatosis gene locus, CYLD, in sporadic skin adnexal tumours.
AIM The gene for familial cylindromatosis (CYLD) has been localised to chromosome 16q, and has recently been cloned. Loss of heterozygosity (LOH) at 16q has also been demonstrated in sporadic cylindromas. The aim of this study was to investigate whether CYLD plays a role in the development of other skin appendage tumours. METHODS A total of 55 cases of skin adnexal tumours, comprising 12 diff...
