Gene structure and QPCR data for genes that are neighed expressed in a tissue-specific manner nor in a tissue-restricted manner, however, with validated alternatively spliced variants. QPCR data presented as changes in fold ratios between expressions of two splice variants in different adult pig tissues for the genes: BSCL2, HNRPLL, PPP3CC and RBM4. Data are normalised with a reference gene index. Values are geometric means ± Geometric S.E.M.; N = 4 animals. The highest expressed splice variant in the majority of the tissues is used as the numerator and the less expressed splice variant is used as the denominator. The highest expressed splice variant is shown in the upper part of the "Gene" column and the less expressed splice variant is showed in the lower part of the "Gene" column. *sequence that have not been defined as exon in any other species.
