Genes affected

PDIA6 (HGNC:30168): (protein disulfide isomerase family A member 6) This gene encodes a member of the disulfide isomerase (PDI) family of endoplasmic reticulum (ER) proteins that catalyze protein folding and thiol-disulfide interchange reactions. The encoded protein has an N-terminal ER-signal sequence, two catalytically active thioredoxin (TRX) domains, a TRX-like domain, and a C-terminal ER-retention sequence. This protein inhibits the aggregation of misfolded proteins and exhibits both isomerase and chaperone activity. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2016]

The c.784G>T (p.V262L) alteration is located in exon 8 (coding exon 8) of the PDIA6 gene. This alteration results from a G to T substitution at nucleotide position 784, causing the valine (V) at amino acid position 262 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
