Genes affected

REPS1 (HGNC:15578): (RALBP1 associated Eps domain containing 1) This gene encodes a signaling adaptor protein with two EH domains that interacts with proteins that participate in signaling, endocytosis and cytoskeletal changes. The encoded protein has been found in association with intersectin 1 and Src homology 3-domain growth factor receptor-bound 2-like (endophilin) interacting protein 1 when intersectin 1 was isolated from clathrin-coated pits. The encoded protein has also been shown to interact with amphiphysin, a cytoplasmic protein at the surface of synaptic vesicles. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2014]

The c.2204C>T (p.S735F) alteration is located in exon 18 (coding exon 18) of the REPS1 gene. This alteration results from a C to T substitution at nucleotide position 2204, causing the serine (S) at amino acid position 735 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 736 of the REPS1 protein (p.Ser736Phe). This variant is present in population databases (rs200224403, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with REPS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2357703). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt REPS1 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
