Genes affected

REPS2 (HGNC:9963): (RALBP1 associated Eps domain containing 2) The product of this gene is part of a protein complex that regulates the endocytosis of growth factor receptors. The encoded protein directly interacts with a GTPase activating protein that functions downstream of the small G protein Ral. Its expression can negatively affect receptor internalization and inhibit growth factor signaling. Multiple transcript variants encoding different isoforms have been found for this gene.

The c.488T>G (p.I163S) alteration is located in exon 3 (coding exon 3) of the REPS2 gene. This alteration results from a T to G substitution at nucleotide position 488, causing the isoleucine (I) at amino acid position 163 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
