Genes affected

ERLEC1 (HGNC:25222): (endoplasmic reticulum lectin 1) This gene encodes a resident endoplasmic reticulum (ER) protein that functions in N-glycan recognition. This protein is thought to be involved in ER-associated degradation via its interaction with the membrane-associated ubiquitin ligase complex. It also functions as a regulator of multiple cellular stress-response pathways in a manner that promotes metastatic cell survival. Alternative splicing results in multiple transcript variants. A related pseudogene has been identified on chromosome 21. [provided by RefSeq, Aug 2011]

GPR75-ASB3 (HGNC:):

GPR75-ASB3 links:

ASB3 (HGNC:16013): (ankyrin repeat and SOCS box containing 3) The protein encoded by this gene is a member of the ankyrin repeat and SOCS box-containing (ASB) family of proteins. They contain ankyrin repeat sequence and SOCS box domain. The SOCS box serves to couple suppressor of cytokine signalling (SOCS) proteins and their binding partners with the elongin B and C complex, possibly targeting them for degradation. Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Jan 2011]

The c.953T>C (p.V318A) alteration is located in exon 9 (coding exon 9) of the ERLEC1 gene. This alteration results from a T to C substitution at nucleotide position 953, causing the valine (V) at amino acid position 318 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
