Genes associate with ceramide metabolism were identified in C. gigas by searching of publicly available databases. Sequences assembled from short read archive data and expressed sequence tags were given a Gene ID code that corresponds to the sequence in the Additional file1. For each of these contiguous sequences, the top BLASTx hit description, corresponding species, and e-value are provided. Two genes that matched to a single EST each in GenBank (sphingomyelin synthase and ceramide synthase) are denoted with their respective GenBank Accession Numbers since they are not represented as a contig of multiple ESTs. An additional four genes [GenBank: HQ425699, HQ425701, HQ425703, and HQ425705] have been previously characterized in C. gigas[20].
