Genes affected

DDAH1 (HGNC:2715): (dimethylarginine dimethylaminohydrolase 1) This gene belongs to the dimethylarginine dimethylaminohydrolase (DDAH) gene family. The encoded enzyme plays a role in nitric oxide generation by regulating cellular concentrations of methylarginines, which in turn inhibit nitric oxide synthase activity.

BCL10-AS1 (HGNC:55868): (BCL10 antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.77).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.386 is higher than 0.05.
