In prostate tumour samples, the only observed AIP alterations were two previously unreported variants, likely to be silent polymorphisms, in one sample each (Table 1): G12G (36G>A) coding for glycine in exon 1 in a primary cancer sample and C238C (714C>T) coding for cystein in exon 5 in a hormone-refractory cancer sample. The gene discussed is AIP; the disease is prostate neoplasm.
