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]
TDRD6-AS1 (HGNC:56119): (TDRD6 and SLC25A27 antisense RNA 1)
