Genes affected
RGP1 (HGNC:21965): (RGP1 homolog, RAB6A GEF complex partner 1) Enables guanyl-nucleotide exchange factor activity and small GTPase binding activity. Involved in negative regulation of cellular protein catabolic process; positive regulation of GTPase activity; and retrograde transport, endosome to Golgi. Located in cytosol and plasma membrane. Part of Ric1-Rgp1 guanyl-nucleotide exchange factor complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 22, 2024The c.623G>T (p.C208F) alteration is located in exon 6 (coding exon 5) of the RGP1 gene. This alteration results from a G to T substitution at nucleotide position 623, causing the cysteine (C) at amino acid position 208 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
