Genes affected

ATF6B (HGNC:2349): (activating transcription factor 6 beta) The protein encoded by this gene is a transcription factor in the unfolded protein response (UPR) pathway during ER stress. Either as a homodimer or as a heterodimer with ATF6-alpha, the encoded protein binds to the ER stress response element, interacting with nuclear transcription factor Y to activate UPR target genes. The protein is normally found in the membrane of the endoplasmic reticulum; however, under ER stress, the N-terminal cytoplasmic domain is cleaved from the rest of the protein and translocates to the nucleus. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]

Ambry Genetics

Feb 15, 2023

The c.958G>C (p.E320Q) alteration is located in exon 9 (coding exon 9) of the ATF6B gene. This alteration results from a G to C substitution at nucleotide position 958, causing the glutamic acid (E) at amino acid position 320 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
