Genes affected

RHBDF1 (HGNC:20561): (rhomboid 5 homolog 1) Predicted to enable growth factor binding activity and serine-type endopeptidase activity. Involved in several processes, including negative regulation of protein secretion; regulation of epidermal growth factor receptor signaling pathway; and regulation of proteasomal protein catabolic process. Located in Golgi membrane and endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.794G>A (p.R265Q) alteration is located in exon 6 (coding exon 5) of the RHBDF1 gene. This alteration results from a G to A substitution at nucleotide position 794, causing the arginine (R) at amino acid position 265 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
