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.502A>G (p.T168A) alteration is located in exon 3 (coding exon 3) of the RPN1 gene. This alteration results from a A to G substitution at nucleotide position 502, causing the threonine (T) at amino acid position 168 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
