Genes affected

TDRD6 (HGNC:21339): (tudor domain containing 6) This gene encodes a tudor domain-containing protein and component of the chromatoid body, a type of ribonucleoprotein granule present in male germ cells. Studies in rodents have demonstrated a role for the encoded protein in spermiogenesis and the nonsense mediated decay (NMD) pathway. This protein is a major autoantigen in human patients with autoimmune polyendocrine syndrome type 1 (APS1). [provided by RefSeq, Oct 2016]

Ambry Genetics

Sep 21, 2023

The c.243G>T (p.W81C) alteration is located in exon 1 (coding exon 1) of the TDRD6 gene. This alteration results from a G to T substitution at nucleotide position 243, causing the tryptophan (W) at amino acid position 81 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
