Nature of Mutation
DNA sequencing using the SOLiD technique identified a G to A transition at position 95 of the Stoml3 transcript in exon 2 of 7 total exons. Two transcripts of the Stoml3 gene are displayed on Ensembl. The mutated nucleotide causes a phenylalanine to serine substitution at amino acid 32 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
Protein Function and Prediction
The Stoml3  gene encodes for a 287 amino acid single-pass type III membrane protein found in olfactory epithelium.  STOML3 is detected in lipid rafts, apical membranes and olfactory cilia (Uniprot Q6PE84).
The F32S change occurs in the transmembrane domain and is predicted to be probably benign by the PolyPhen program.
