MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the G protein-coupled receptor family and regulates brain cortical patterning. The encoded protein binds specifically to transglutaminase 2, a component of tissue and tumor stroma implicated as an inhibitor of tumor progression. Mutations in this gene are associated with a brain malformation known as bilateral frontoparietal polymicrogyria. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2014]
PHENOTYPE: Mice homozygous for a null allele exhibit neuronal ectopias in the frontoparietal cortex due to disruptions in the pial basement membrane. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified a T to C transition at position 569 of the Gpr56 transcript in exon 4 of 14 total exons. The mutated nucleotide causes a valine to alanine substitution at amino acid 168 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction

The Gpr56 gene encodes a 687amino acid G-protein coupled receptor (GPCR) that may be involved in cell-cell interactions. All GPCRs are seven-pass membrane proteins and signal through heterotrimic G proteins. The extracellular N-terminal region (aa 26-402) contains a mucin-like domain and a cysteine box (Uniprot Q8K209). Mice homozygous for a null allele exhibit neuronal ectopias in the frontoparietal cortex due to disruptions in the pial basement membrane. Homozygous mutations in humans result in bilateral frontoparietal polymicrogyria (BFPP; OMIM 606854). All of the human missense mutations affected extracellular portions of the protein and were found mostly in the N-terminal region.

The V168A change is located in the N-terminal region of the protein, and is predicted to be benign by the PolyPhen program.
