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.

This sequence change creates a premature translational stop signal (p.Tyr511*) in the ADGRG1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ADGRG1 are known to be pathogenic (PMID: 15044805, 20929962). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ADGRG1-related conditions. ClinVar contains an entry for this variant (Variation ID: 158621). For these reasons, this variant has been classified as Pathogenic. -
