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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2024The c.155A>G (p.Q52R) alteration is located in exon 2 (coding exon 1) of the RABGEF1 gene. This alteration results from a A to G substitution at nucleotide position 155, causing the glutamine (Q) at amino acid position 52 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
