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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1573G>C (p.A525P) alteration is located in exon 9 (coding exon 9) of the RPN1 gene. This alteration results from a G to C substitution at nucleotide position 1573, causing the alanine (A) at amino acid position 525 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
