Genes affected

RAPGEF6 (HGNC:20655): (Rap guanine nucleotide exchange factor 6) Enables several functions, including GTP-dependent protein binding activity; guanyl-nucleotide exchange factor activity; and phosphatidic acid binding activity. Involved in microvillus assembly; positive regulation of GTPase activity; and protein localization to plasma membrane. Located in several cellular components, including apical plasma membrane; centrosome; and endocytic vesicle. [provided by Alliance of Genome Resources, Apr 2022]

The c.4825G>C (p.V1609L) alteration is located in exon 29 (coding exon 29) of the RAPGEF6 gene. This alteration results from a G to C substitution at nucleotide position 4825, causing the valine (V) at amino acid position 1609 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
