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.200C>G (p.T67R) alteration is located in exon 1 (coding exon 1) of the REPS2 gene. This alteration results from a C to G substitution at nucleotide position 200, causing the threonine (T) at amino acid position 67 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
