Genes affected

DERL1 (HGNC:28454): (derlin 1) The protein encoded by this gene is a member of the derlin family. Members of this family participate in the ER-associated degradation response and retrotranslocate misfolded or unfolded proteins from the ER lumen to the cytosol for proteasomal degradation. This protein recognizes substrate in the ER and works in a complex to retrotranslocate it across the ER membrane into the cytosol. This protein may select cystic fibrosis transmembrane conductance regulator protein (CFTR) for degradation as well as unfolded proteins in Alzheimer's disease. Alternative splicing results in multiple transcript variants that encode different protein isoforms. [provided by RefSeq, Aug 2012]

Jan 23, 2023

The c.748G>A (p.D250N) alteration is located in exon 8 (coding exon 8) of the DERL1 gene. This alteration results from a G to A substitution at nucleotide position 748, causing the aspartic acid (D) at amino acid position 250 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
