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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2023The c.376C>T (p.R126W) alteration is located in exon 2 (coding exon 2) of the REPS2 gene. This alteration results from a C to T substitution at nucleotide position 376, causing the arginine (R) at amino acid position 126 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
