The frequency of homozygous deletions of CDKN2A detected by MLPA in ESFT cell lines (44%) and primary tumours (10%) is consistent with the literature using more established methods including Southern blot (Kovar et al, 1997; Tsuchiya et al, 2000; Wei et al, 2000), PCR (Tsuchiya et al, 2000), and fluorescent in situ hybridisation (Huang et al, 2005). Here, CDKN2A is linked to neoplasm.
