Genes affected

ADGRL3 (HGNC:20974): (adhesion G protein-coupled receptor L3) This gene encodes a member of the latrophilin subfamily of G-protein coupled receptors (GPCR). Latrophilins may function in both cell adhesion and signal transduction. In experiments with non-human species, endogenous proteolytic cleavage within a cysteine-rich GPS (G-protein-coupled-receptor proteolysis site) domain resulted in two subunits (a large extracellular N-terminal cell adhesion subunit and a subunit with substantial similarity to the secretin/calcitonin family of GPCRs) being non-covalently bound at the cell membrane.

The c.3994C>G (p.P1332A) alteration is located in exon 23 (coding exon 23) of the ADGRL3 gene. This alteration results from a C to G substitution at nucleotide position 3994, causing the proline (P) at amino acid position 1332 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
