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 GeneticsApr 08, 2024The c.241C>T (p.L81F) alteration is located in exon 3 (coding exon 2) of the RABGEF1 gene. This alteration results from a C to T substitution at nucleotide position 241, causing the leucine (L) at amino acid position 81 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
