Condition	Inheritance	Intervention Categories	Intervention/Rationale	Manifestation Categories	References
Thyroid dyshormonogenesis 6	AD/AR	Endocrine	Individuals may manifest with congenital or subclinical hypothyroidism, and medical treatment (with thyroid hormone replacement) may be effective	Endocrine	12110737; 16134168; 21565790; 23239635; 23457309
Heterozygous variants have been reported as typically resulting in transient congenital hypothyroidism, while bi-allelic variants have been described as more frequently causing more severe and permanent forms of disease

Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the DUOX2 gene is commonly pathogenic or not. These statistics are base on transcript: NM_001363711.2. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Generates hydrogen peroxide which is required for the activity of thyroid peroxidase/TPO and lactoperoxidase/LPO. Plays a role in thyroid hormones synthesis and lactoperoxidase-mediated antimicrobial defense at the surface of mucosa. May have its own peroxidase activity through its N-terminal peroxidase-like domain. {ECO:0000269|PubMed:12824283}.
• Disease: DISEASE: Thyroid dyshormonogenesis 6 (TDH6) [MIM:607200]: A disorder due to a defective conversion of accumulated iodide to organically bound iodine. The iodide organification defect can be partial or complete. {ECO:0000269|PubMed:12110737, ECO:0000269|PubMed:16134168, ECO:0000269|PubMed:16322276, ECO:0000269|PubMed:20187165}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Note=Defects in DUOX2 may play a role in the pathogenesis of very early onset inflammatory bowel disease (VEOIBD), a chronic, relapsing inflammation of the gastrointestinal tract with a complex etiology diagnosed before 6 years of age. VEOIBD is subdivided into Crohn disease and ulcerative colitis phenotypes. Crohn disease may affect any part of the gastrointestinal tract from the mouth to the anus, but the phenotype of children with onset of Crohn disease occurring younger than the age of 10 is predominantly colonic, with a lower risk of ileal disease. Bowel inflammation is transmural and discontinuous; it may contain granulomas or be associated with intestinal or perianal fistulas. In contrast, in ulcerative colitis, the inflammation is continuous and limited to rectal and colonic mucosal layers; fistulas and granulomas are not observed. Both diseases include extraintestinal inflammation of the skin, eyes, or joints. {ECO:0000269|PubMed:26301257}.
