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.2382G>C (p.K794N) alteration is located in exon 18 (coding exon 17) of the RHBDF1 gene. This alteration results from a G to C substitution at nucleotide position 2382, causing the lysine (K) at amino acid position 794 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
