Genes affected

SEL1L (HGNC:10717): (SEL1L adaptor subunit of SYVN1 ubiquitin ligase) The protein encoded by this gene is part of a protein complex required for the retrotranslocation or dislocation of misfolded proteins from the endoplasmic reticulum lumen to the cytosol, where they are degraded by the proteasome in a ubiquitin-dependent manner. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

The c.1864G>A (p.A622T) alteration is located in exon 1 (coding exon 1) of the SEL1L gene. This alteration results from a G to A substitution at nucleotide position 1864, causing the alanine (A) at amino acid position 622 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
