FGFR3 and posterior cortical atrophy: Analogous findings were obtained where either a short or long variant of each gene was confirmed by RT-PCR to be enriched or uniquely expressed in AA (TSC2-S, ITGA4-L, MET-L, BAK1-L) or EA PCa (FGFR3-L, ITGA4-S, MET-S, NF1-S, BAK1-S) (Fig. 3b; Supplementary Fig. 4 for quantitative RT-PCR (qRT-PCR) results from n=22–25 AA and n=21–24 EA PCa specimens).
