Genes affected

RFNG (HGNC:9974): (RFNG O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase) Predicted to enable O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase activity. Predicted to be involved in regulation of Notch signaling pathway. Predicted to act upstream of or within positive regulation of Notch signaling pathway and positive regulation of protein binding activity. Predicted to be integral component of Golgi membrane.

GPS1 (HGNC:4549): (G protein pathway suppressor 1) This gene is known to suppress G-protein and mitogen-activated signal transduction in mammalian cells. The encoded protein shares significant similarity with Arabidopsis FUS6, which is a regulator of light-mediated signal transduction in plant cells. [provided by RefSeq, Mar 2016]

Ambry Genetics

Aug 16, 2022

The c.215G>C (p.G72A) alteration is located in exon 1 (coding exon 1) of the RFNG gene. This alteration results from a G to C substitution at nucleotide position 215, causing the glycine (G) at amino acid position 72 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
