Genes affected
ADGRG1 (HGNC:4512): (adhesion G protein-coupled receptor G1) 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.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.761G>A (p.R254Q) alteration is located in exon 6 (coding exon 4) of the ADGRG1 gene. This alteration results from a G to A substitution at nucleotide position 761, causing the arginine (R) at amino acid position 254 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
