Genes affected

RABGEF1 (HGNC:17676): (RAB guanine nucleotide exchange factor 1) RABGEF1 forms a complex with rabaptin-5 (RABPT5; MIM 603616) that is required for endocytic membrane fusion, and it serves as a specific guanine nucleotide exchange factor (GEF) for RAB5 (RAB5A; MIM 179512) (Horiuchi et al., 1997 [PubMed 9323142]).[supplied by OMIM, Mar 2010]

Jun 23, 2023

The c.1171C>T (p.P391S) alteration is located in exon 9 (coding exon 8) of the RABGEF1 gene. This alteration results from a C to T substitution at nucleotide position 1171, causing the proline (P) at amino acid position 391 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
