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]

Sep 11, 2024

The c.199G>A (p.E67K) alteration is located in exon 3 (coding exon 2) of the RABGEF1 gene. This alteration results from a G to A substitution at nucleotide position 199, causing the glutamic acid (E) at amino acid position 67 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
