Genes affected

ADGRE1 (HGNC:3336): (adhesion G protein-coupled receptor E1) This gene encodes a protein that has a domain resembling seven transmembrane G protein-coupled hormone receptors (7TM receptors) at its C-terminus. The N-terminus of the encoded protein has six EGF-like modules, separated from the transmembrane segments by a serine/threonine-rich domain, a feature reminiscent of mucin-like, single-span, integral membrane glycoproteins with adhesive properties. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

The c.692T>A (p.I231N) alteration is located in exon 7 (coding exon 7) of the ADGRE1 gene. This alteration results from a T to A substitution at nucleotide position 692, causing the isoleucine (I) at amino acid position 231 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
