Genes affected

ELL3 (HGNC:23113): (elongation factor for RNA polymerase II 3) Predicted to enable cis-regulatory region sequence-specific DNA binding activity. Involved in positive regulation of transcription, DNA-templated and transcription by RNA polymerase II. Located in several cellular components, including chromosome; cytosol; and nuclear lumen. Part of transcription elongation factor complex. [provided by Alliance of Genome Resources, Apr 2022]

ELL3 links:

PDIA3 (HGNC:4606): (protein disulfide isomerase family A member 3) This gene encodes a protein of the endoplasmic reticulum that interacts with lectin chaperones calreticulin and calnexin to modulate folding of newly synthesized glycoproteins. The protein was once thought to be a phospholipase; however, it has been demonstrated that the protein actually has protein disulfide isomerase activity. It is thought that complexes of lectins and this protein mediate protein folding by promoting formation of disulfide bonds in their glycoprotein substrates. This protein also functions as a molecular chaperone that prevents the formation of protein aggregates. [provided by RefSeq, Dec 2016]

The c.1111C>T (p.R371C) alteration is located in exon 11 (coding exon 11) of the ELL3 gene. This alteration results from a C to T substitution at nucleotide position 1111, causing the arginine (R) at amino acid position 371 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
