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]
TBC1D31 (HGNC:30888): (TBC1 domain family member 31) Located in centrosome. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.67G>C (p.V23L) alteration is located in exon 1 (coding exon 1) of the DERL1 gene. This alteration results from a G to C substitution at nucleotide position 67, causing the valine (V) at amino acid position 23 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
