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.4093G>A (p.E1365K) alteration is located in exon 23 (coding exon 23) of the ADGRL3 gene. This alteration results from a G to A substitution at nucleotide position 4093, causing the glutamic acid (E) at amino acid position 1365 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
