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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.146A>G (p.E49G) alteration is located in exon 1 (coding exon 1) of the TDRD6 gene. This alteration results from a A to G substitution at nucleotide position 146, causing the glutamic acid (E) at amino acid position 49 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
