Genes affected

RPN1 (HGNC:10381): (ribophorin I) This gene encodes a type I integral membrane protein found only in the rough endoplasmic reticulum. The encoded protein is part of an N-oligosaccharyl transferase complex that links high mannose oligosaccharides to asparagine residues found in the Asn-X-Ser/Thr consensus motif of nascent polypeptide chains. This protein forms part of the regulatory subunit of the 26S proteasome and may mediate binding of ubiquitin-like domains to this proteasome. [provided by RefSeq, Jul 2008]

The c.1391C>G (p.T464S) alteration is located in exon 8 (coding exon 8) of the RPN1 gene. This alteration results from a C to G substitution at nucleotide position 1391, causing the threonine (T) at amino acid position 464 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
