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]

The c.784G>A (p.E262K) alteration is located in exon 8 (coding exon 7) of the RGP1 gene. This alteration results from a G to A substitution at nucleotide position 784, causing the glutamic acid (E) at amino acid position 262 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
