Deleterious effects of a non-synonymous SNP in FAB2C . FAB2C (Glyma14g27990) encodes one out of three stearoyl-acyl-carrier-protein desaturases that convert stearic acid into oleic acid. The FAB2C allele in FAM94-41 contains the variant nucleotide G instead of the reference nucleotide A in the first nucleotide position of codon 77. This non-synonymous SNP results in an amino acid change from the acidic polar aspartic acid (Asp, encoded by GAC) to the polar asparagine (Asn, encoded by AAC), which renders the protein non-functional. FAM94-41 exhibits an elevated stearic acid phenotype as less stearic acid is converted into oleic acid.
