Nature of Mutation

DNA sequencing using the SOLiD technique identified a T to C transition at base pair 54482248 in the Genbank genomic region NC_000077 (Build 37.1) for the Rapgef6 gene on Chromosome 11 (GTATGACATG ->GTATGACACG). The mutation is located within intron 21 from the ATG exon, nine nucleotides from the previous exon. Multiple transcripts of the Rapgef6 gene are displayed on Ensembl and Vega. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction

The Rapgef6 gene encodes multiple isoforms of a Rap guanine nucleotide exchange factor (GEF). GEFs can activate G-alpha proteins by exchanging bound GDP for free GTP. The 1601 amino acid isoform contains a cyclic nucleotide-monophosphate binding domain at residues 280-398, an N-terminal Ras-GEF motif at residues 412-525, a protein-interacting PDZ domain at residues 540-612, a Ras associating domain at amino acids 749-835, and a Ras-GEF domain at amino acids 856-1138 (Uniprot Q5NCJ0; SMART). Mice homozygous for a null allele exhibit an enlarged spleen, increased IgE and IgG levels and altered cytokine production.
