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]

The c.1351G>A (p.V451I) alteration is located in exon 12 (coding exon 12) of the ATF6B gene. This alteration results from a G to A substitution at nucleotide position 1351, causing the valine (V) at amino acid position 451 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
