(a)
MRAS has 6 different splice isoforms in the RefSeq database (top), comprising 9 exons (numbered 1–9 inclusively). mRNA levels measured by 9 non-overlapping microarray probes in exons 5–9 were significantly associated with dosage of minor alleles of SNP rs13078961 in human DRGs as discovery (green), blood as replication (blue), and TMD caseness (red). (b) The relative position of microarray probes at 3’ UTR of MRAS (exon 9) associated with SNP rs13078961 in human DRGs (green), blood (blue), and TMD caseness (red). Coordinates are UCSC hg19. For brevity, only the last two digits of probe identifiers are shown; whole probe identifiers are: PSR030135xx.
