Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to G transition at base pair 149619221 in the Genbank genomic region NC_000070 (Build 37.1) for the Eno1 gene on Chromosome 4 (CTTCTCCAAG ->CTTCTCCGAG).  The mutation is located within intron 5 from the ATG exon, three nucleotides to the next exon. The Eno1 gene contains 12 total exons using Genbank record NM_023119. Multiple transcripts of the Eno1gene are displayed on Ensembl and Vega.  The mutation has been confirmed by DNA sequencing using the Sanger method (see trace files for B5639).

Protein Function and Prediction

The Eno1 gene encodes the 434 amino acid alpha-enolase.  Enolase is a glycolytic enzyme (2-phospho-D-glycerate hydrolyase) and is a mulltifunctional enzyme involved in growth control, hypoxia tolerance and allergic responses. The protein serves as a receptor and activator of plasminogen on the cell surface of several cell-types such as leukocytes and neurons, and stimulates immunoglobulin production. The enolase isoforms can form homodimers or heterodimers that are cell-type and development-specific (Uniprot P17182). Homozygous knockout mice exhibit growth arrest and embryonic lethality at approximately E6.5.
