Genes affected

DIO3OS (HGNC:20348): (DIO3 opposite strand upstream RNA) The mouse and human DIO3OS and DIO3 (MIM 601038) genes overlap and are transcribed in opposite directions. The mouse Dio3 gene is imprinted from the paternal allele during fetal development, suggesting that DIO3OS is a noncoding gene that may have a role in maintaining monoallelic expression of DIO3 (Hernandez et al., 2004 [PubMed 14962667]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.285 is higher than 0.05.
