The spp mutation corresponds to an A to T transversion in the donor splice site of intron 5 (GTAAGT -> GTTAGT; position 19359 in the Genbank genomic region NC_000079). It is predicted to result in skipping of the 133-nucleotide 5th exon (of 10 total exons), shifting the reading frame so aberrant amino acids are encoded after aa position 74 and creating a premature stop codon that would terminate the protein after aa 76.
