Genes affected

FGD6 (HGNC:21740): (FYVE, RhoGEF and PH domain containing 6) Predicted to enable guanyl-nucleotide exchange factor activity and small GTPase binding activity. Predicted to be involved in several processes, including filopodium assembly; regulation of GTPase activity; and regulation of cell shape. Predicted to be located in Golgi apparatus; lamellipodium; and ruffle. Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The c.2231G>C (p.C744S) alteration is located in exon 2 (coding exon 2) of the FGD6 gene. This alteration results from a G to C substitution at nucleotide position 2231, causing the cysteine (C) at amino acid position 744 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
