Genes affected

PDILT (HGNC:27338): (protein disulfide isomerase like, testis expressed) 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 has an N-terminal ER-signal sequence, two thioredoxin (TRX) domains with non-classical Ser-Lys-Gln-Ser and Ser-Lys-Lys-Cys motifs, respectively, two TRX-like domains, and a C-terminal ER-retention sequence. The protein lacks oxidoreductase activity in vitro and probably functions as a chaperone. This gene's expression appears to be limited to the testis. [provided by RefSeq, Dec 2016]

The c.1219G>A (p.D407N) alteration is located in exon 9 (coding exon 8) of the PDILT gene. This alteration results from a G to A substitution at nucleotide position 1219, causing the aspartic acid (D) at amino acid position 407 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
